“…In recent years, with the aim of combining the advantages of homogeneous and heterogeneous catalytic processes, nanoparticles have been employed due to their high surface area and facile recovery . Important nano‐heterogeneous supports such as metal oxides, carbon nanotubes, ionic liquids, molecular sieves (SBA‐15, MCM‐41 and MCM‐48), alumina, peptide nanofibers, silica nanoparticles, polymers, graphene oxide and heteropoly acids have been employed for the heterogenization of homogeneous catalysts .…”

A boehmite@tryptophan-Pd nanoparticulate catalyst was prepared by a simple, fast and convenient route. The nanomaterial was characterized using various techniques and employed as a thermally stable catalyst for Heck, Stille and Suzuki cross-coupling reactions. Optimized conditions for these reactions are described. The catalyst could be isolated, post-reaction, by simple filtration and recycled for several consecutive cycles without a notable change in its activity.

“…Carbon materials are widely used as catalyst supports, adsorbents, electrodes for supercapacitors, reinforcing fillers of polymers, fuel cell electrodes, biosensors, for the delivery of therapeutic preparations in cells, etc. [1][2][3][4]. Such a wide application of carbon materials is based on the variety of their morphological structures (nanotubes, nanofibers, amorphous carbon, and others), electronic properties, chemical stability in aggressive media, inertness toward the supported catalytically active component, the possibility of recovering the deposited noble metals by burning of the support, etc.…”

The role of acid treatment of Taunit carbon nanotubes in the formation of oxygen-containing functional groups on its surface as well as morphological and textural properties was studied. Acid treatment was carried out in an HNO3 solution or its mixture with H2SO4 under mild conditions (85 °C/1 h) with subsequent washing with distilled water or without washing. Properties of the initial and oxidized samples were investigated using elemental carbon, hydrogen, nitrogen, oxygen (CHNO) analysis, BET (Brunauer-Emmett-Teller) determination of surface area, X-ray diffraction, Raman and Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy, and hydrogen temperature-programmed reduction. Treatment with HNO3 and HNO3/H2SO4 mixture was shown to be efficient for the formation of various oxygen-containing groups on the Taunit surface; therewith, the water washing step also contributed to functionalization of the surface. Depending on the oxidant, acid treatment increased graphite and oxygen content in the samples by a factor of 3‒4.5. Treatment with HNO3 without water washing exerted a weak effect on the graphite structure ordering, the concentration of aliphatic groups was high as compared to other oxidation conditions. Treatment of Taunit with the HNO3/H2SO4 mixture, on the contrary, increased the number of defects in graphite layers and decreased the concentration of aliphatic structures.

“…Rice-husk To characterize morphology and crystalline structure [17,146] a temperature lower than 200 °C would give a higher yield of hydrochar rather than temperature beyond 200 °C [195]. Thermodynamic properties of the hydrochar have revealed that its yield and properties can be expressed as a function of dose-response, and hence there occur significant variations in the properties and yield by a change in the temperature [56,58,189,[192][193][194].…”

A Comprehensive Review on Hydrothermal Carbonization of Biomass and its Applications

Hydrothermal carbonization (HTC) has gained a lot of interest in the last few years for the process production of hydrochar from the different kinds of biological materials such as agricultural waste. Therefore, a thorough review of the literature on HTC has been conducted, which is more energy-efficient and involves hydrochar preparation at a lower temperature without any specific requirements for pressure. This review article primarily differentiates between the hydrochar and biochar developed from various sources. Also, a comparative analysis has been done to evaluate the maximum efficiency of hydrochar production. The various parameters, which influence the hydrochar yield to include pH, temperature, the concentration of the modifying agent, duration of exposure, salt, and phenolic compounds, have also been highlighted in this review. The scale-up processes for industrial level hydrochar production, along with bioreactor designs, have also been discussed. We have also focused on various applications of hydrochar, such as adsorbent in wastewater treatment, carbon sequestration, gas adsorption and in the field of agriculture for soil amendment. The adsorption effects of hydrochar towards the partial and proportionate adsorption of heavy metals and hazardous chemicals have been depicted. This review of the literature clearly illustrates the role of HTC in environmental remediation of soil, air and water and its usage in various industries.
