Ultrasmall nanoparticles on nanocarbons enhance the electrocatalytic nitrogen reduction (NRR) efficiency. Herein, we demonstrate a novel method for depositing MoO nanoparticles on defective graphene, achieving a high faradaic efficiency (FE) of 43.1% at -0.2 V RHE.

Pyroelectrodynamic therapy (PEDT) of tumors faces challenges due to its low electrocatalytic efficiency at mild temperature and the potential for off-target toxicity to healthy tissue. To overcome these issues, we have engineered pyroelectric nanoparticles (NPs) that feature a pH-triggered heterojunction structure and tumor-selective reactive oxidative species (ROS) production, faclitating synergistic PEDT and mild photothermal therapy (PTT). Herein, molybdenum trioxide (MoO) was deposited in-situ on the surface of tetragonal BaTiO (tBT) to create tBT@MO.

This work presents the development and validation of a highly sulfur-selective nanomaterial based on silica doped with active metal phases for the desulfurization of heavy crude oils. Initially, various transition element oxide nanoparticles (FeO, NiO, ZnO, MoO, CuO, and AgO) were synthesized and screened for sulfur adsorption in batch mode. AgO and CuO exhibited the highest removal efficiencies─24% and 21%, respectively─at an adsorbent-to-crude oil ratio of 2:40 (g/g).

Oxygen deficient molybdenum oxide nanosheet (Od-MO Nshs) was synthesised by hydrothermal method and its peroxidase-like activity was established with 3,3',5,5'-Tetramethylbenzidine-(TMB) and o-phenylenediamine dihydrochloride-(OPD) as a co-substrate in presence of Hydrogen peroxide (HO) and catalytic parameters were compared with horseradish peroxidase-(HRP) enzyme. Optimization was carried out for physical and chemical parameters. Synthesised nanoparticles-(NPs) were characterized for size, shape, composition oxidation state etc.

Cadmium oxide (CdO)-incorporating molybdenum trioxide (MoO) nanocomposites were synthesized using a facile hydrothermal method by varying the CdO content (1%, 3%, and 5%) to comprehend the influence of CdO concentration on the electrochemical performance of MoO. The structural and morphological properties of the synthesized nanomaterials were characterized using X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). XRD showed that MoO has an orthorhombic structure, and FE-SEM showed that it has a nanobelt shape (0.

For NiFe-based precatalysts, there is a general consensus that they will undergo reconstruction to generate NiFe (oxy)hydroxides as real active sites during the electrochemical oxygen evolution reaction (OER), but the current understanding of the reconstruction process is still far from satisfactory. Herein, iron phosphates/molybdates on nickel foams (FPM/NF, = 5, 7, 10, 20) were prepared via a coprecipitation method, where although both MoO and PO undergo anion exchange during the activation process, i.e.
