The present work shows the development of efficient electrocatalysts for OER and ORR based on combination Ni Co oxides with or without NiCo<sub>2</sub>O<sub>4</sub>, blended graphene nanoribbons (GNRs) composed low content Pt.
Nowadays there is a huge search for alternative materials that are relatively cheaper and highly abundant in nature which can be used the development of electrolyzers suitable hydrogen production.
Abstract The hydrogen evolution and nitrite reduction reactions are key to producing green ammonia. Antenna–reactor nanoparticles hold promise improve the performances of these transformations under visible‐light excitation, by combining plasmonic catalytic materials. However, current materials involve compromising either on activity or enhancement also lack control reaction selectivity. Here, we demonstrate that ultralow loadings non‐uniform surface segregation component optimize...
Electrocatalytic production of H2O2 via a two-electron oxygen reduction reaction (ORR-2e-) is regarded as highly promising decentralized and environmentally friendly mechanism for the this important chemical commodity. However, underlying challenges related to development catalytic materials that contain zero or low content noble metals are relatively more active, selective, resistant long-term use have become huge obstacle electroproduction on commercial industrial scales. The present study...
It is well known that the benchmark electrocatalysts for OER in alkaline solution are RuO2 and IrO2; however, high cost, scarcity, instability of these metal oxides impede their ample use processes, this has fueled search cheap Earth-abundant elements which equally efficient application as OER. The present work reports hydrothermal calcination methods synthesis nanocomposites made up Ni and/or Co salts urea combination with MoSe2 MoS2 stable solution. NiCoMoSe, NiCoMo, CoMoSeS, CoMo...
Plasmonic photocatalysis has been limited by the high cost and scalability of plasmonic materials, such as Ag Au. By focusing on earth-abundant photocatalyst/plasmonic materials (HxMoO3) Pd a catalyst, we addressed these challenges developing solventless mechanochemical synthesis Pd/HxMoO3 optimizing photocatalytic activities in visible range. We investigated effect HxMoO3 band gap excitation (at 427 nm), interband transitions localized surface plasmon resonance (LSPR) 640 nm) over toward...

Materials that lead to devices with tunable responses the morphology are a potential opportunity. Tellurium, growing material class possessing higher electronic conductivity, has recently been seen exhibit same in transition-metal-based complexes when combined toward wider energy applications. However, it rarely engineered and implemented for morphology-dependent low-dimensional (LD) structures catalytic reactions. Herein, first time, we provide novel approach designing dimension variable...
Remarkable, high stability, simple, and inexpensive noble metal-free materials as electrocatalysts with the best TOF (312 900 s<sup>−1</sup>, corrected by Faraday efficiency) for H<sub>2</sub>production.
