“…In addition, further attention should be given to topological structure design for active catalysts (actual determination of selectivity should be noted [54]) with high-current density, long-term run, and depressing the decomposition of H 2 O 2 at high overpotentials. The catalysts may be low stability at high-current density, and reasonable experiments and characterization techniques should be applied to find the factors of material degradation [14] and provide targeted solutions. Combined with rational device design, the two-electron ORR process is expected to have other commercial applications in the future.…”

Electrochemical synthesis of hydrogen peroxide (H 2 O 2) provides a clean and safe technology for large-scale H 2 O 2 production. The core of this project is the development of highly active and highly selective catalysts. Recent studies demonstrate that carbonaceous materials are favorable catalysts because of their low-cost and tunable surface structures. This brief review first summarizes the strategies of carbonaceous material engineering for selective two-electron O 2 reduction reaction and discusses potential mechanisms. In addition, several device designs using carbonaceous materials as catalysts for H 2 O 2 production are introduced. Finally, research directions are proposed for practical application and performance improvement.

“…However, finite reserves and high costs of precious metals limit their large-scale applications [12]. Alternatively, carbonaceous materials have been identified as efficient catalysts because of their abundance, high stability in electrochemical reactions, and tunable surface and structural properties [12][13][14].…”

“…It is also notable that both the activity and pathway selectivity vary along with the change of applied potential. Besides, the electrochemical CO 2 RR performance including both activity and pathway relies on not only electrolyte species and the nanostructure of the electrocatalysts, but also the material species 66b. According to the selectivity toward the major reduced product, electrocatalysts for CO 2 RR are generally classified into three categories: i) CO (e.g., Au and Zn); ii) formate (e.g., In, Sn); iii) hydrocarbons (e.g., Cu) .…”

Layered metal hydroxides (LMHs) are regarded as a novel and important class of inorganic functional materials. They have unique layered structure and variable chemical compositions that can be readily tuned. In this review, summarized are the recent advances of synthetic routes to the LMHs with designed morphology, composition, and function for electrocatalysis. Versatile products can be readily derived by hybridization, anion‐exchange, surface modification, self‐assembly, etc. More importantly, LMHs can be artificially exfoliated into unilamellar nanosheets with a molecular‐level thickness of about 1 nm versus 2D lateral size in submicrometer or micrometer scale. Molecular‐scale assembly can be then applied to fabricate superlattice‐like composites and functional nanofilms with high quality. The hydroxides can be transformed into oxides, nitrides, or other compounds via different preparation procedures, which can further extend their application prospects. In this regard, the most promising electrocatalysis‐related applications of LMHs and their derivatives are reviewed, such as oxygen evolution reaction, oxygen reduction reaction, hydrogen evolution reaction, CO2 reduction reaction, alcohol or urea electrooxidation, etc. At last, future challenges are also discussed from the aspect of synthesis and application, as well as encouraging advancements are anticipated.

“…Most H 2 O 2 is industrially synthesized by the anthraquinone oxidation process, which requires a complicated operation, including hydrogenation, oxidation of anthrahydroquinone by O 2 , and extraction and purification of H 2 O 2 3 . High-energy consumption, substantial organic by-product waste, and transportation constraints are the main problems in the application of H 2 O 2 4,5 . As an alternative, many efforts have been made to develop efficient and in situ synthesis methods.…”

Highly efficient electrosynthesis of hydrogen peroxide on a superhydrophobic three-phase interface by natural air diffusion

et al. 2020

Hydrogen peroxide (H 2 O 2) synthesis by electrochemical oxygen reduction reaction has attracted great attention as a green substitute for anthraquinone process. However, low oxygen utilization efficiency (<1%) and high energy consumption remain obstacles. Herein we propose a superhydrophobic natural air diffusion electrode (NADE) to greatly improve the oxygen diffusion coefficient at the cathode about 5.7 times as compared to the normal gas diffusion electrode (GDE) system. NADE allows the oxygen to be naturally diffused to the reaction interface, eliminating the need to pump oxygen/air to overcome the resistance of the gas diffusion layer, resulting in fast H 2 O 2 production (101.67 mg h-1 cm-2) with a high oxygen utilization efficiency (44.5%-64.9%). Long-term operation stability of NADE and its high current efficiency under high current density indicate great potential to replace normal GDE for H 2 O 2 electrosynthesis and environmental remediation on an industrial scale.
