“…In this regard, Anderson et al have defined a "triangular concept" for catalyst design. [52,53] This ideas have been extended to electro-and photo-catalysis considering the electronic and optical properties of the materials, which play a crucial role for these applications ( Figure 5). Nowadays, catalyst preparation methodologies can be optimized thanks to the molecular-scale characterization techniques such as in-situ IR and Raman spectroscopies, in-situ X-ray diffraction and neutron-based techniques.…”

“…[94] The Fischer-Tropsch synthesis (FTS), which can be defined as the process to convert a mixture of carbon monoxide and hydrogen (syngas) derived from biomass or solid organic matter to valuable hydrocarbons, is another example of the multiple applications of catalytic sciences. [53] This process is employed to obtain various fuels and chemicals. Optimization Figure 6.…”

“…Particularly, bioconjugates based on metal oxide nanoparticles and enzymes are arising materials, which have shown promising catalytic results in oxidative polymerization reactions. By combining environmental advantages of enzyme‐catalyzed reactions, such as moderate operating conditions and high selectivity, with the easy recovery and reusability of metal oxide nanoparticles, new horizons can be opened for the design of upgraded catalysts …”

Environmental catalysis plays a crucial role in sustainable development by the design of novel catalytic materials and technologies. Several environmental issues are addressed by catalytic processes such as decomposition of pollutants for air, water and soil remediation, hydrogen production, CO2 reduction and biomass valorization, just to name a few. This contribution aims to provide a general overview of the main concepts and current advances in the environmental catalysis field. Special attention has been paid to photocatalysis and electrocatalysis, as sub‐areas of catalysis with tremendous potential in sustainable applications, in particular with regard to the promotion of sustainable energies. In this contribution, the partnership between Catalysis and Green Chemistry is presented, in a comprehensive way, as an open research line which is imperative and decisive for a more sustainable future.

“…Basing on the mechanical-assisted approach described above, another bioconjugate was synthetized using a redox-active protein and Fe 2 O 3 nanoparticles. For the synthesis, dopamine (DA) previously coated with Fe 2 O 3 particles (DA-Fe 2 O 3 ) was functionalized with hemoglobin, using two successive mechanicalassisted steps [46]. The so-prepared materials were employed as catalysts to polymerize ortho-, meta-and para-substituted phenylenediamines.…”

Compared to standard time and solvent consuming procedures, mechanically-assisted processes offer numerous environmentally-friendly advantages for nano-catalytically active materials design. Mechanochemistry displays high reproducibility, simplicity, cleanliness and versatility, avoiding, in most cases, the use of any solvent. Moreover, mechanically-assisted procedures are normally faster and cheaper as compared to conventional processes. Due to these outstanding characteristics, mechanochemistry has evolved as an exceptional technique for the synthesis of novel and advanced catalysts designed for a large range of applications. The literature reports numerous works showing that mechanosynthetic procedures offer more promising paths than traditional solvent-based techniques. This review aims to disclose the latest advances in the mechanochemical assisted synthesis of catalytically active materials, focusing on nanocatalysts designed for biomass conversion and on bio-based catalysts.

“…Moreover, the use of heterogeneous catalytic systems usually requires a filtration or centrifugation step to recover the catalyst. In this regard, magnetic nanoparticles (MNPs) has attracted a great interest since they can be easily separated from the reaction mixture by using a magnetic external field and reused for several cycles [10][11][12]. Nonetheless, maintaining the stability of these particles for a long time without agglomeration or precipitation is still a challenge [13,14].…”

An organocatalytic system based on an unprecedented proline analogue and iron oxide magnetic nanoparticles (Prn/Fe 2 O 3 @SiO 2) was designed and employed in vanillin production from isoeugenol and vanillyl alcohol. Full characterization of the obtained catalyst revealed the successful functionalization of the nanoparticle surface with the organic moieties. The activity of the magnetic bifunctional material was compared with its proton-unexchanged counterpart. Interestingly, the oxidation of isoeugenol resulted in being highly dependent on the acidic functionalities of the organocatalyst. Nonetheless, the catalytic performance of the proton-unexchanged catalyst suggested that the acidic and basic sites of the Prn/Fe 2 O 3 @SiO 2 exhibited a synergic effect, giving rise to higher conversion and selectivity. The presence of bifunctional groups in the proline analogue, together with the magnetic properties of the iron oxide nanoparticles, could lead to high efficiency, versatility, recoverability, and reusability.
