Abstract
The electrochemical production of hydrogen peroxide is enjoying an increasing attention by endowing a promising alternative to traditional complex and energy-intensive anthraquinone process. Engineering efficient electrocatalysts with desirable activity, selectivity and stability toward H2O2 electrocatalysis have achieved great progress yet still challenging. Currently, single atom-based electrocatalysts have been evidenced as one of the most efficient candidates for their remarkable activity and selectivity. However, isolated Pt atoms on different supports could tell different stories toward oxygen reduction reaction (ORR) via two or four electron transfer path due to their distinct metal-support interactions. Here, single Pt atoms are successfully anchored on the surface of AuCu ultrathin nanowire aerogels (denoted as AuCu@SA-Pt) through kinetically controlled galvanic replacement reaction. The composition-optimized AuCu@SA-Pt-144 behaved a two electron transfer path other than four as evidenced by a sm...

Shifting electrochemical oxygen reduction reaction (ORR) via two-electron pathway becomes increasingly crucial as an alternative/green method for hydrogen peroxide (H2 O2 ) generation. Here, the development of 2e- ORR catalysts in recent years is reviewed, in aspects of reaction mechanism exploration, types of high-performance catalysts, factors to influence catalytic performance, and potential applications of 2e- ORR. Based on the previous theoretical and experimental studies, the underlying 2e...

Different techniques that enable the selective microstructure design of aerogels without the use of additives are presented. For this, aerogels were prepared from platinum nanoparticle solutions using the cryoaerogelation method, and respective impacts of different freezing times, freezing media, and freezing temperatures were investigated with electron microscopy as well as inductively coupled plasma optical emission spectroscopy. The use of lower freezing temperatures, freezing media with high...

Carbon materials slightly doped with heteroatoms such as nitrogen (N-RFC) or sulfur (S-RFC) are investigated as active catalysts for the electrochemical bioelectronic oxygen reduction reaction (ORR) to H 2 O 2 . Mesoporous carbons with wide, accessible pores were prepared by pyrolysis of a resorcinol-formaldehyde resin using a PEO-b-PS block copolymer as a sacrificial templating agent and the nitrogen and sulfur doping were accomplished in a second thermal treatment employing 1,10-phenanthroline...

Noble metal-based nanomaterials have been a hot research topic during the past few decades. Particularly, self-assembled porous architectures have triggered tremendous interest. At the forefront of porous nanostructures, there exists a research endeavor of noble metal aerogels (NMAs), which are unique in terms of macroscopic assembly systems and three-dimensional (3D) porous network nanostructures. Combining excellent features of noble metals and the unique structural traits of porous nanostruct...

The electroproduction of H2O2 through 2e oxygen reduction reaction (ORR) as an alternative strategy for the conventional anthraquinone process is highly energy-efficient and environment-friendly. Different kinds of electrocatalysts with high selectivity, activity, and stability have been recently reported, and are an essential part of the whole electroproduction process of H2O2. In this review, we expound the ORR mechanism and introduce some methods to screen out potential electrocatalysts throu...
