As an eco-friendly alternative to the conventional anthraquinone process, electrochemical production of hydrogen peroxide (H2O2) through oxygen reduction reaction has been attracting attention. The goal this work is derive a carbon-based material from carbon dioxide (CO2) achieve high performance in H2O2 production. Doping heterogeneous element such as on catalyst mainly explored increase selectivity and activity, but little research conducted enhancing catalytic activity with oxidized boron insertion. This study proposes porous materials synthesized CO2 electrocatalysts. Polyethylene oxide (PEO) was thermally treated together boron-oxygen bonding sites. result, having functional groups BC2O BCO2 showed (1.25 mA cm−2) (∼90 %) over wide voltage range two-electron ORR (Oxygen Reduction Reaction) at alkaline media. Furthermore, H-cell where 0.4 V vs. RHE applied, average rate maintained 452.96 mmol g−1 h−1 for four hours faraday efficiency 90 %.

Functional thin films play a critical role in efforts toward efficient devices for energy conversion and storage, as well low-loss electronics. These need to be manufactured at scale, cost-effectively, with precision. Atmospheric pressure spatial atomic layer deposition (AP-SALD) has emerged promising technique fulfilling these requirements. AP-SALD replicates the subnanometer control of thickness, uniformity, crystallinity, conformality substrate featured conventional atomic-layer-deposited films, but important advantage depositing growth rates that are orders magnitude higher. This review discusses opportunities advantages opens up energy-conversion storage devices, In particular, features recent work on using AP-SALD-grown photovoltaics, light-emitting diodes, self-powered sensors, photoelectrochemical cells batteries, transparent conductive materials epitaxial films. Perspectives future unexplored electronics also discussed. Published by American Physical Society 2025

Published: June 14, 2024

Abstract Manufacturing the biochar‐derived 2e‐electron oxygen reduction (2e‐ORR) electrocatalyst from sustainable biomass promises a cost‐effective alternative for typical petroleum‐based resources, but still suffers inferior catalytic activity and low 2e‐ORR selectivity. Here, study demonstrates simple effective strategy achieving high‐performance Co‐ZIF‐engineered cellulose electrocatalyst, enabling in situ growth of nanostructured ZIF‐67 particles around abundant hydrophilic oxygen‐containing micro‐scale fibers. Through one‐step pyrolysis at 900 °C cellulose‐Co‐ZIF substrate, high‐porosity carbonous Co‐ZIF‐CC catalyst is obtained that possesses active sites carbon defects, facilitating progress H 2 O production. By utilizing as reaction gas, it can electrochemically generate concentration attaining up to 555.1 mg L −1 , outperforming nearly five‐fold increase compared using air, also showing about maximin thirty times higher exiting biochar‐based electrocatalysts biomass. The proposed breakthroughs next generation renewable bioresources with low‐cost, economic ecology, beyond wide potential applications other electrocatalysts.
