A review on recent developments in electrochemical hydrogen peroxide synthesis with a critical assessment of perspectives and strategies

Electrochemical hydrogen peroxide synthesis using two-electron oxygen electrochemistry is an intriguing alternative to currently dominating environmentally unfriendly and potentially hazardous anthraquinone process noble metals catalysed direct synthesis. Electrocatalytic reduction reaction (ORR) water oxidation (WOR) are the source of electrochemical generation. Various electrocatalysts have been used for same were characterized several electroanalytical, chemical, spectroscopic chromatographic tools. Though there a few reviews summarizing recent developments in this field, none them unified approaches catalysts' design, criticized ambiguities flaws methods evaluation, emphasized role electrolyte engineering. Hence, we dedicated review discuss trends performance optimization, evaluation perspectives their appropriateness opportunities with In addition, particularized discussions on fundamental electrochemistry, additional precise screening, solution chemistry synthesized also presented. Thus, discloses state-of-the-art unpresented view highlighting challenges, opportunities, perspectives.
