Two-dimensional MoS2 nanosheets (NSs) with high active site density were designed for the hydrogen evolution reaction (HER) through a microdomain method. The effect of annealing temperature on microstructure and HER performance NSs was examined, plausible relation between stack structures catalysts their also explored. NS electrocatalyst obtained at 550 °C reveals best relatively small Tafel slope 68 mV/dec. Both exposed surface area are very important providing large amount sites. present...
This work investigates the degradation of 5-hydroxymethylfurfural (HMF) in an alkaline electrolyte, enabling “indirect” electrooxidation HMF at unprecedentedly high substrate and base concentrations improved atom economy.
Abstract Scandium oxide (Sc 2 O 3 ) is considered as omnipotent “Industrial Ajinomoto” and holds promise in catalytic applications. However, rarely little attention paid to its electrochemistry. Here, the first nanocasting design of high‐surface area Sc with abundant oxygen vacancies (mesoporous V ‐Sc for efficient electrochemical biomass valorization reported. In case electro‐oxidation 5‐hydroxymethylfurfural (HMF) 2,5‐furandicarboxylic acid (FDCA), quantitative HMF conversion, high yield,...
Abstract The plastic waste issue has posed a series of formidable challenges for the ecological environment and human health. While conventional recycling strategies often lead to down‐cycling, electrochemical strategy recovering valuable monomers enables an ideal, circular economy. Here corrosion synthesized single atom Pt 1 /Ni(OH) 2 electrocatalyst with part‐per‐million noble loading highly efficient selective upcycling polyethylene terephthalate (PET) into chemicals (potassium diformate...
Hydrogen generated in electrolyzers is discussed as a key element future energy scenarios, but oxygen evolution the standard anode reaction complex multi-step requiring high overpotential. At same time,it does not add value-the typically released into atmosphere. Alternative reactions which can proceed at similar current densities hydrogen are, therefore, of highest interest. We have discovered high-performance electrode based on earth-abundant elements synthesized presence H2 O2 , able to...
Abstract H 2 generation from methanol‐water mixtures often requires high pressure and temperature (200–300 °C). However, CO can be easily generated poison the catalytic system under such temperature. Therefore, it is highly desirable to develop efficient systems for production methanol at room temperature, even sub‐zero temperatures. Herein, carbon nanotube‐supported Pt nanocomposites are designed synthesized as high‐performance nano‐catalysts, via stabilization of nanoparticles onto...
Abstract The rational design of efficient bimetallic nanoparticle (NP) catalysts is challenging due to the lack theoretical understanding active components and insights into mechanisms a specific reaction. Here, we report nanoreactors comprising hollow carbon sphere‐confined PtNi NPs (PtNi@HCS) as highly for hydrogen generation via ammonia borane hydrolysis in water. Using both density functional theory calculations molecular dynamics simulations, effects an combination critical synergistic...
The design and application of electrocatalysts based on Earth-abundant transition-metal oxides for biomass valorization remain relatively underexplored.

Abstract 2,5‐Furandicarboxylic acid (FDCA) synthesis holds significant importance for both bio‐polymer production and emerging sustainable bio‐based alternatives environmental energy applications. Here, a metal‐free carbonaceous material—that is, biomass substrate 5‐hydroxymethylfurfural‐derived graphene‐like nitrogen doped porous carbon sheet (GNPCH)—and its application as new catalyst electrochemical FDCA is presented. The study scrutinized the catalytic principles, demonstrated surprising...
The rational design of highly efficient PtNi@ZIF-8 nanocatalyst and the understanding hydrogen generation process for selective complete decomposition hydrazine borane (HB) are disclosed.
Hydrogen (H2) production is a key challenge for green carbon-free sustainable energy. Among the H2 evolution methods from H-rich materials, ammonia borane (AB) solvolysis stands as privileged source under ambient and sub-ambient conditions given its stability, non-toxicity, solubility in protic solvents, provided suitable optimized nanocatalysts are used. In this paper dedicated to Prof. Avelino Corma, we comparatively review AB hydrolysis alcoholysis (mostly methanolysis) terms of...
Ferrocene (Fc) in ether reduces HAuCl4 water within seconds under ambient conditions air upon stirring, forming ferricinium chloride stabilized water-soluble 20 nm gold nanoparticles (AuNPs) that are redispersible the presence of poly(N-vinylmethylpyrrolidone) or NaBH4 + thiol. After reduction with yielding Fc and 26 sodium poly(hydroxyborate) AuNPs, core size no longer changes following reactions thiols providing (RS)nAuNPs.
Renewable electricity-powered electrooxidation of 5-hydroxymethylfurfural (HMFOR) to FDCA offers a green and sustainable approach producing an essential monomer for bio-polymers, provided that highly efficient electrocatalyst is present. Herein, we show the doping scandium (Sc) into NiFe-LDH (Sc-NiFe-LDH) considerably promotes HMFOR by enhancing formation high-valence Ni
In spite of the fact that remarkable developments are achieved in design and development novel nanocatalysts for H2 release upon dimethylamineborane hydrolysis, an "on-off" switch demand-based evolution hydrolysis is still a matter supreme importance, however. Herein, we synthesized string MoS2 nanosheet-supported RuNi bimetallic nanohybrids (RuxNi1-x/MoS2), by fixation nanoparticles at surface, 30 °C. For safely effectively generating, transporting, storing gas, selective on-demand over...
