Hydrogen peroxide, which is a green oxidant and fuel, is produced by a two-electron/two-proton reduction of dioxygen, two-electron/two-proton oxidation of water, or a combination of four-electron/four-proton or/and two-electron/two-proton oxidation of water and two-electron/two-proton reduction of dioxygen. There are many reports on electrocatalysts for selective two-electron/two-proton reduction of dioxygen to produce hydrogen peroxide instead of four-electron/four-proton reduction of dioxygen to produce water. As compared with the two-electron/two-proton reduction of dioxygen to produce hydrogen peroxide, fewer catalysts are known for the selective two-electron/two-proton oxidation of water to produce hydrogen peroxide instead of four-electron/four-proton oxidation of water to evolve dioxygen. Thus, solar-driven production of hydrogen peroxide mainly consists of the catalytic four-electron/four-proton oxidation of water and the catalytic two-electron/two-proton reduction of dioxygen. The overall reaction is the solar-driven oxidation of water by dioxygen to produce hydrogen peroxide. Either or both the four-electron/four-proton or/and the two-electron/two-proton oxidation of water and the two-electron/two-proton reduction of dioxygen requires photocatalysts. The yield of hydrogen peroxide is improved when the compartment for the photocatalytic four-electron/four-proton or/and two-electron/two-proton oxidation of water is separated from that for the catalytic two-electron/two-proton reduction of dioxygen using a two-compartment cell separated by a membrane. The overall solar-driven oxidation of water by dioxygen, which is the greenest oxidant, to produce hydrogen peroxide can be combined with catalytic oxidation of various substrates by hydrogen peroxide.

“…Nanoarrays empirical performance metrics, particularly peak power densities and cell stability, underscore their potential to redefine FCs' applications. [102] Furthermore, studies on Ni-Pd core-shell nanoparticles and microfiber cathodes in magnesium-H 2 O 2 semi-FCs have provided insights into their respective applications, with a focus on their unique fabrication techniques and performance metrics. In another study, the impact of Ni-Metal core-shell nanoparticles on multiwalled carbon nanotube (MWCNT) support was explored, specifically for borohydride oxidation in alkaline solutions.…”

Catalytic valveless micropumps, and membraneless fuel cells are the class of devices that utilize the decomposition of hydrogen peroxide (H2O2) into water and oxygen. Nonetheless, a significant obstacle that endures within the discipline pertains to the pragmatic open circuit potential (OCP) of hydrogen peroxide FCs (H2O2 FCs), which fails to meet the theoretical OCP. Additionally, bubble formation significantly contributes to this disparity, as it disrupts the electrolyte's uniformity and interferes with reaction dynamics. In addition, issues such as catalyst degradation and poor kinetics can impact the overall cell efficiency. The development of high‐performance H2O2‐FCs necessitates the incorporation of selective electrocatalysts with a high surface area. However, porous micro‐structures of the electrode impedes the transport of fuel and the removal of reaction byproducts, thereby hindering the attainment of technologically significant rates. To address these challenges, including bubble formation, the review highlights the potential of integrating electrokinetic and bubble‐driven micropumps. An alternative approach involves the spatiotemporal separation of fuel and oxidizer through the use of laminar flow‐based fuel cell (LFFC). The present review addresses multifaceted challenges of H2O2‐powered FCs, and proposes integration of electrokinetic and bubble‐driven micropumps, emphasizing the critical role of bubble management in improving H2O2 FC performance.

“…For example, Yang et al constructed a DHPFC [97] in which the cathode and the anode were both Pd particles electrodeposited onto carbon fibre cloth as discussed further below. Recently, cheaper alternatives to the Pd cathodes such as Ni and Co catalysts deposited on TiC nanowires [98] and nickel ferric ferrocyanide nanoparticles [99] showing similar or higher power densities have been demonstrated in two-compartment fuel cells.…”

This review introduces the concept of direct H2O2 fuel cells and discusses the merits of these systems in comparison with other ‘clean-energy’ fuels. Through electrochemical methods, H2O2 fuel can be generated from environmentally benign energy sources such as wind and solar. It also produces only water and oxygen when it is utilised in a direct H2O2 fuel cell, making it a fully reversible system. The electrochemical methods for H2O2 production are discussed here as well as the recent research aimed at increasing the efficiency and power of direct H2O2 fuel cells.
