“…The D‐band to the G‐band intensity ratios (I D /I G , understood via the collective areas of the band) are 1.62, 1.72, 2.31, 2.42, 2.40 and 2.38 for MC, Au‐MC‐SI, NMC, Au‐NMC‐SI, Au‐NMC‐DP and Au‐NMC‐IW, respectively. This result revealed that imperfection in the graphite‐like sheets was raised on increasing the N‐content of the catalyst as well as after Au metal loading [67,76–79] …”

“…The graphitic nature of the carbon samples (MC, NMC and supported Au catalysts) was studied by Raman spectroscopy (Figure 1d). Raman spectra consists of D‐band (1335 cm −1 )and G‐band (1590 cm −1 ),which are attributesof disordered graphitic carbon materials [76–79,83,84a] . The G‐band showcases the graphitic establishment of carbon samples, while the D‐band represent defects and suggesting an insufficient crystalline assembly of the carbons [76–79,83,84a] .…”

“…The FT‐IR peak located at 2925 cm −1 was allotted to the stretching frequency of C−H bonds [76–79] . A broad peak within the 3150–3560 cm −1 range was recognized for NMC and this peak was associated with the N−H and O−H bonds stretching vibrational frequency [76–79] . However, this peak (in the range of 3150–3560 cm −1 ) in MC was accredited to the O−H bond stretching vibrational frequency.…”

“…The XPS analysis was performed to look at carefully the type of nitrogen species present on NMC surface as well as to investigate the support‐metal interactions. The carbon 1 s XPS peak is observed for NMC and MC nearly at 284.6 eV, which was linked to the graphitic carbons,signifying that the largely carbon atoms in samples were accumulated in a conjugated honeycomb type architecture (Figure 2a) [77] . The peaks associated to carbon, oxygen and nitrogen (C 1s, O 1s, N 1s) were noticed in NMC, but simply carbon and oxygen (C 1s, O 1s) were witness in MC (Figure 2a).…”

“…Previously, we have reported the highly efficient Pd nanoparticles catalyst supported on nitrogen‐doped mesoporous carbon (NMC) for chemoselective hydrogenation of CA to HCA at ambient reaction conditions [76] . Recently, we have also discuss the efficiency of NMC supported active Ru metal nanoparticles catalysts for the conversion of biomass‐derived 5‐hydroxymethylfurfural to 2,5‐dimethylfuran and furfural to 2‐methylfuran as a result of catalytic transfer hydrogenation using 2‐propanol as source of hydrogen [77] . Moreover, our research group also discuss efficacy of NMC supported Ru metal catalysts for H 2 generation owing to aqueous phase reforming of glycerol [67] .…”

Several supported gold metal catalysts with different Au nanoparticles sizes were prepared and evaluated for the chemoselective hydrogenation of cinnamaldehyde (CA) to cinnamyl alcohol (CAL). To investigate the structure‐activity relationship, stability of catalyst, heterogeneity and recyclability, the structural characteristics of materials and Au catalysts (fresh and spent catalysts) were studied by employing variety of physico‐chemical techniques. The interrelationship among Au nanoparticles size (nm) with turnover frequency (h−1) of Au catalysts has also been explored. Among the various Au catalysts tested, nitrogen‐doped mesoporous carbon (NMC) supported Au catalyst having homogeneously dispersed (78.8%) Au nanoparticles (1.6 nm) synthesized by sol‐immobilization method (Au‐NMC‐SI) demonstrated improved catalytic activity affording 78% CAL selectivity and 94.2% CA conversion without using any promoter. Moreover, Au‐NMC‐SI catalyst exhibited good recyclability and stability. The catalyst synthesis approach described in this investigation opens up a novel strategy for the design of highly efficient metal nano‐catalysts supported on NMC materials.

consumption combined with a resource efficient circular economy approach, with the final goal of minimizing the impact of health, safety, security and environment.In the design of a greener future, the replacement of depleting sources with renewable ones is at the center of a sustainable development. [2] Biomass is a natural, abundant, renewable, carbon-neutral source; its use represents a promising strategy to address the need for substituting fossil feedstock in the preparation of chemicals, fuels, and materials, besides energy production. [3][4][5][6][7][8][9][10][11][12][13][14] The major issues that limit the large-scale utilization of biomass in fuel production are the differences in cost and process efficiencies compared to those for fossil fuels. [15] After the Covid-19 crisis, this aspect has become even more evident, as reported by the International Agency of Energy, ultimately causing the first contraction in biofuel production over the past two decades. [16] The reduced transport fuel demand and the decreased petroleum-based fuel prices have transitorily lowered the economic interest for biofuel production. In this pandemic and emergency scenario, therefore, has emerged even more clearly the importance of developing efficient strategies for biomass conversion into fuels, making economically attractive the use of environmentally friendly renewable energy systems (Figure 1). [17] Among the plethora of biomass transformations, hydrogenation and hydrodeoxygenation reactions are widely used for decreasing the oxygen content of biomass-derived platforms to increase their potential as fuels. [18][19][20] In this context, as well as in the challenging goal of creating a decarbonized energy system, hydrogen plays a prominent role in the chemical industry. [21][22][23][24] It is important to notice that the vast majority of the worldwide hydrogen production (45-65 Mt/year) features a significant CO 2 footprint as a consequence of different hydrocarbon reforming processes (i.e., steam-reforming of fossil fuels, thermal cracking of natural gas, solar-thermal reforming of methane) or of coal gasification. [25] Several efforts have been directed during the past years toward the definition of possible effective approaches to a green H 2 production by water splitting. [26][27][28][29][30][31] To date, however, both water electrolysis and photo-driven water splitting are economically and energetically unfavorable, with a long way ahead to hold the promise of a zero-carbon energy system. Indeed, the associated energy demand as well as the low market prices of oxygen, inevitably co-produced from water electrolysis, hinder the shaping of a large-scale employment of this technology.Liquid organic hydrogen carriers (LOHCs) are attractive materials for their ability to generate in situ hydrogen that may be directly used to produce target biofuel precursors, fuels or fuel additives. Indeed, the replacement of fossil feedstock is an urgent necessity for shifting toward a carbon neutral energy economy. Several desired chemica...

The conversion of lignocellulosic biomass into platform chemicals and fuels by metal single atoms is a new domain in solid catalysis research. Unlike the conventional catalysis route, single‐atom catalysts (SAC) proliferate maximum utilization efficiency, high catalytic activity, and good selectivity to the desired product with an ultralow loading of the active sites. More strikingly, SAC shows a unique cost‐effective pathway for the conversion of complex sugar molecules to value‐added chemicals in high yield and selectivity, which may be hindered by conventional metal nanoparticles. Primarily, SACs having adjustable active sites could be easily modified using sophisticated synthetic techniques based on their intended reactions. This review covers current research on the use of SACs with a strong emphasis on the fundamentals of catalyst design, and their distinctive activities in each type of reaction (hydrogenation, hydrogenolysis, hydrodeoxygenation, oxidation, and dehydrogenation). Furthermore, the fundamental insights into the superior actions of SACs within the opportunity and prospects for the industrial‐scale synthesis of value‐added products from the lignocelluloses are covered.
