Review on Biomass-Derived Carbon-Based Materials for Electrocatalytic Hydrogen Production: State of the Art and Outlook

Abstract

The increasing demand for sustainable hydrogen production is driven by the rapid expansion of global energy consumption. Electrocatalytic H 2 production is one of the preferred methods for future energy technology. The hydrogen evolution reaction (HER) has attracted extensive attention as an important half-reaction for traditional water electrolysis. However, cost-effective and efficient electrode materials for HER are scarce. Biomass-derived carbon-based materials could offer a promising solution by utilizing biomass waste through rational engineering design, which can address biomass pollution but also enable the synthesis of effective electrocatalytic materials, aligning with the principles of green chemistry. This study provides a comprehensive review of multiple synthetic methods for producing carbon-based materials from biomass, such as pyrolysis, hydrothermal carbonization, ionothermal carbonization, and molten salt carbonization. The diverse applications of these materials in H 2 production are explored. Effective treatment strategies and valuable insights for future biomass-derived carbon-based material design in H 2 production are also presented. This progress contributes to a better understanding of these materials and offers valuable insights for future explorations.

Electronic Structure Effect of PtCo Alloy with Adjustable Compositions for Efficient Methanol Electrooxidation

“…The anodic methanol oxidation reaction (MOR) as an important half-reaction plays a crucial role in methanol-based fuel cells by enabling the direct conversion of methanol into electricity, offering high energy density, fuel efficiency, environmental benefits, and ease of refueling. − However, this oxidation process involves the six-electron transfer and the conversion of multiple intermediates, which result in sluggish reaction kinetics, which is several orders of magnitude slower than the cathodic hydrogen evolution reaction (HER). − Thereafter, the development of efficient and durable anode catalysts is crucial for fuel cell commercialization.…”
