Herein, we synthesized a type of anion/cation co-doped MoO nanosphere as an efficient OER catalyst. The optimized Ni/N-MoO exhibited a lower overpotential of 270 mV at 10 mA cm in 24 h. This work provides a unique direction for the synthesis of efficient and stable MoO-based electrocatalysts for water splitting.

Recent advancements in materials design have driven the scientific community to explore phosphor materials for multifunctional applications. This study presents the multimodal light emission (downshifting - DS, quantum cutting - QC, and upconversion - UC) from Pr/Yb activated NaLa(MoO) phosphors for multifunctional applications. Under blue (449 nm) and NIR (980 nm) excitation, co-doped phosphors emit visible light through DS and UC processes caused by different f-f transitions of Pr ions.

Obtaining a robust electrode composed of Sn-based metal oxides and carbonaceous matrix through nanoscale structure engineering is essential for effectively improving Li-ion batteries' electrochemical performance and stability. Herein, we report a bimetallic MoO-xSnO/Sn nanoparticles uniformly anchored on N, S co-doped graphene nanosheets (MoO-xSnO/Sn@NSG) as an anode electrode for Li-ion battery via a one-step hydrothermal and thermal treatment approach. In the MoO-xSnO/Sn nanocomposite, the generated Sn-O-Mo bond can modulate the electronic and composition structures to improve the intrinsic conductivity of SnO and reinforce the structural stability during cycles.

Alloy-type antimony (Sb) and conversion-type molybdenum (Mo) anodes have attracted extensive attention in the application of lithium-ion batteries (LIBs) owing to their high theoretical capacity. In this study, SbMoO nanowires are prepared via a hydrothermal method and assessed their thermal behavior upon heat treatment, observing an intriguing transformation from nanowire to SbO/MoO nanosheets. To enhance structure stability, the SbMoO nanowires are successfully coated with a polyphosphazene layer (referred to as PZS@SbMoO), which not only preserved the nanowires form but also yielded N/S co-doped carbon-coated SbPO/MoO (NS-C@SbPO/MoO) nanowires following annealing in an inert environment.

The deactivation of selective catalytic reduction (SCR) catalysts caused by alkali metal poisoning remains an insurmountable challenge. In this study, we examined the impact of Na poisoning on the performance of Fe and Mo co-doped TiO (FeMoTiO) catalysts in the SCR reaction and revealed the related alkali resistance mechanism. On the obtained FeMoTiO catalyst, the synergistic catalytic effect of uniformly dispersed FeO and MoO species leads to remarkable catalytic activity, with over 90% NO conversion achieved in a wide temperature range of 210-410 °C.
