“…Alternatively, the modification of BC texture can also improve the output of FTP, particularly after activation [161] or by inserting nitrogen doping. As reported by Bai et al [162], the presence of pyrrolic functionalities improved the selectivity towards long-chain hydrocarbons due to a better adsorption of CO.…”

The development of heterogeneous catalysts is one of the pillars of modern material science. Among all supports, carbonaceous ones are the most popular due to their high surface area, limited cost, and tunable properties. Nevertheless, materials such as carbon black are produced from oil-derived sources lacking in sustainability. Pyrolytic carbon produced from biomass, known as biochar, could represent a valid solution to combine the sustainability and performance of supported catalysts. In this review, we report a comprehensive overview of the most cutting-edge applications of biochar-based catalysts, providing a reference point for both experts and newcomers. This review will provide a description of all possible applications of biochar-based catalysts, proving their sustainability for the widest range of processes.

“…Surface chemistry modifications on biochar significantly influence catalytic activity, as exemplified by Bai et al who introduced nitrogen through urea doping. This alteration modified the electronic structure of the material, enhancing metal dispersion and metal-support interaction, resulting in conversion rates exceeding 90%, with selectivity toward heavier hydrocarbons reaching approximately 50% [80]. Exploring Fe as a catalyst is noteworthy due to its heightened selectivity toward olefins and its inherent water-gas shift activity, thereby augmenting hydrogen content in the feed.…”

This review paper delves into the diverse ways in which carbonaceous resources, sourced from renewable and sustainable origins, can be used in catalytic processes. Renewable carbonaceous materials that come from biomass-derived and waste feedstocks are key to developing more sustainable processes by replacing traditional carbon-based materials. By examining the potential of these renewable carbonaceous materials, this review aims to shed light on their significance in fostering environmentally conscious and sustainable practices within the realm of catalysis. The more important applications identified are biofuel production, tar removal, chemical production, photocatalytic systems, microbial fuel cell electrodes, and oxidation applications. Regarding biofuel production, biochar-supported catalysts have proved to be able to achieve biodiesel production with yields exceeding 70%. Furthermore, hydrochars and activated carbons derived from diverse biomass sources have demonstrated significant tar removal efficiency. For instance, rice husk char exhibited an increased BET surface area from 2.2 m2/g to 141 m2/g after pyrolysis at 600 °C, showcasing its effectiveness in adsorbing phenol and light aromatic hydrocarbons. Concerning chemical production and the oxidation of alcohols, the influence of biochar quantity and pre-calcination temperature on catalytic performance has been proven, achieving selectivity toward benzaldehyde exceeding 70%.

“…Carbon dioxide (CO 2 ) is a major end product of the excess burning of fossil fuels and leads to substantial and probably irreversible changes of the world's climate. 1,2 The hydrogenation of CO 2 to CH 3 OH is a preferable way to utilize the abundant emitted CO 2 , [3][4][5] since CH 3 OH is an important chemical feedstock and can be used as a fuel for internal combustion engineering or as a starting material for the production of liquid hydrocarbon fuels such as olefins. 6 The reaction has two possible mechanisms: 7 À1 ) is assumed to be the main reaction pathway for CH 3 OH synthesis.…”
