Formic acid (FA) is an important platform chemical that has numerous applications in the chemical and agricultural industries, as well as in the leather industry. To date, FA is exclusively produced from fossil raw materials using either carbonylation of methanol or acidolysis of formates. Here, sustainable and environmentally friendly approaches to produce biogenic FA from biomass (e.g., OxFA‐process) are presented and combined with different approaches for the catalytic decomposition of bio‐based FA solutions. Several homogeneous and heterogeneous approaches for the catalytic decomposition of aqueous FA to hydrogen and CO2 are compared for their applicability. Moreover, their technical applications in fuel cells, as energy storage vectors, and as hydrogen storage molecules are discussed.

High activity and stability are crucial for the practical use of electrocatalysts in fuel cells, metal-air batteries, and water electrolysis, including the oxygen reduction reaction, hydrogen evolution reaction, oxygen evolution reaction, and oxidation reactions of formic acid and alcohols. Electrocatalysts based on nitrogen-containing carbon (N-C) materials show promise in catalyzing these reactions; however, there is no systematic review of strategies for the engineering of active and stable N-C-based electrocatalysts. Herein, a comprehensive comparison of recently reported N-C-based electrocatalysts regarding both electrocatalytic activity and long-term stability is presented. In the first part of this review, the relationships between the electrocatalytic reactions and selection of the element to modify the N-C-based materials are discussed. Afterwards, synthesis methods for N-C-based electrocatalysts are summarized, and strategies for the synthesis of highly stable N-C-based electrocatalysts are presented. Multiple tables containing data on crucial parameters for both electrocatalytic activity and stability are displayed in this review. Finally, constructing M-N moieties is proposed as the most promising engineering strategy for stable N-C-based electrocatalysts.

equilibrium is shifted, usually resulting in a higher conversion of substrates. Today, immobilizing chemo-and biocatalysts on solid materials to fabricate heterogeneous biohybrid catalysts for cascade reactions has attracted growing interests because of the easy products' separation and simplified catalysts reuse. On the other hand, because of the co-immobilization of different catalysts on the same support, diffusion limitation of intermediates between active sites is reduced, which promotes the overall reaction efficiency in the one-pot process. To date, mesoporous silica, [4] metal-organic frameworks (MOFs), [5] reduced graphene oxide, [6] and polymeric matrices [7] have been utilized as supports for preparing biohybrid catalysts. It was found that intrinsic properties of these supports have a significant impact on the stability and distribution of immobilized chemocatalysts, while the compatibility between carriers and enzymes still remains a concern since enzymes are vulnerable in in vitro environment. Therefore, the judicial selection of solid supports is vitally important, and the task of seeking for new solid supports for developing biohybrid catalysts featuring new functions continues.In the past decade, carbon nitride (C 3 N 4 ) has emerged as a promising material for its outstanding performances in photocatalysis [8] and electrochemistry. [9] Besides, it has been also utilized for bioimaging and biomedical applications, where its good biocompatibility was verified through various methods,The exploration of effective platforms for immobilizing chemo-and biocatalysts to develop biohybrid catalysts is an attractive subject of practical interest. In this work, carbon nitride (C 3 N 4 ) is used for the first time as a platform for the immobilization of metal catalyst (Pd nanoparticles) and biocatalyst (Candida antarctica lipase B, CalB) in a facile manner to prepare biohybrid catalyst. The optimal biohybrid catalyst inherits the intrinsic performance of both Pd nanoparticles and CalB, and shows high activity in the one-pot cascade reaction converting benzaldehyde to benzyl hexanoate at room temperature. With this proof of concept, it is expected that C 3 N 4 can be utilized for immobilizing more types of chemo-and biocatalysts for perspective applications.
