“…However, the wide reduction and oxidation peaks were different from the reports, which might be ascribed to the role of the MoN coating . Meanwhile, MoN presented the conversion reaction with Li + (eq ); the cathodic peak at 1.5 V corresponded to the conversion reaction of MoN with Li + overlaps, while the anodic peak at 1.23 V was attributed to the Li + released from Li x N . The first two and the twentieth charge–discharge curves of MoO 2 @MoN/NF at a current density of 0.2 A g –1 over a potential range of 0.01–3.0 V are shown in Figure b.…”

“…In addition, it is interesting that MoN also has superior properties such as high Pt-like electrocatalytic activities, chemical stability, and great conductivity for LIBs and water splitting. Abbas et al synthesized MoN in nitrogen-doped carbon nanotubes (CNTs), which presented the reversible capacity of 1323 mA h g –1 after 200 cycles at a current density of 100 mA g –1 .

The design and synthesis of a heterostructure as well as binder-free electrodes or electrocatalysts with a porous nanostructure for enhancing electrochemical performance of lithium ion batteries and water splitting are still significant challenges to scientists. Here, for the first time, an in-situ synthesis of the porous petal-like MoN nanolayer-coated MoO2 heterojunction (MoO2@MoN) on commercial nickel foam (NF) by a localized nitrided transformation method as both a binder-free electrode for LIBs and an electrocatalyst for water splitting was performed. The in-situ formation of the MoN nanolayer could create a MoO2@MoN heterostructure, therefore enhancing the electronic conductivity and the electron/ion transfer. The XRD and XPS measurements confirmed the wonderful reversibility of the MoN layer during lithiation/delithiation cycling, which effectively promoted the long-life cycling performance (1190.1 mA h g–1 after 500 cycles at the current density of 0.5 A g–1). Meanwhile, the MoO2@MoN/NF/LiFePO4 full cell displayed stable capacity after 100 cycles. Moreover, the product also showed the improved electrocatalytic activity for hydrogen evolution and oxygen evolution. The excellent results suggest that our work opens a simple in-situ heterojunction formation pathway for the synthesis of other multifunctional materials applied in energy conversion and storage.

“…[35,43,45] In Figure 4d, the two peaks at 230.2 and 233.2 eV with the energy separation of 3.0 eV correspond to Mo3d 5/2 and Mo3d 3/2 states of Mo 4 + , while the peaks at 235.9 eV and 232.3 eV correspond to Mo 6 + , which may be caused by the partial oxidation of MoO 2 . [16,[46][47][48] In the O 1s spectrum ( Figure S7), the peaks at 530.8 eV and 530.2 eV correspond to MoÀ O and SnÀ O bonds, respectively. The peaks at 532.1 eV and 533.0 eV may be due to the formation of CÀ OÀ Mo bond and C=O bond.…”

SnO2@MoO2/carbon hollow nanospheres are successfully fabricated by coating a Mo‐polydopamine chelate precursor on SiO2@SnO2 nanospheres, with subsequent annealing and HF corrosion. In the unique nanocomposites, the external carbon layer with MoO2 nanoparticles and a SnO2 hollow inner layer as the skeleton can not only enhance electronic conductivity, but also reinforce the shell of the hollow nanocomposites while preventing the aggregation of SnO2 and MoO2 nanoparticles during intensive cycles, thus enhancing the structural integrity, rate capability and cyclic stability. In virtue of the respective roles and synergistic effects of the three nanocomponents, the unique ternary nanocomposites possess an initial discharge capacity of 1097 mAhg−1, high initial coulombic efficiency of 85 %, and good cyclic performance (725 mAhg−1 after 300 cycles) as anode nanomaterials. The structural design of the MoO2/C layer coating metal‐oxide hollow nanospheres can provide a novel synthetic approach for other hybrid energy nanomaterials with excellent properties.

“…The thermal annealing of ZFN at a temperature range of 800–1000°C under NH 3 atmosphere produces final materials with high stability, methanol tolerance and uniform distribution of Fe and N in carbon matrix ( Figure 12b and c- e). Similarly, molybdenum nitride (Mo 2 N) nanoparticles could be dispersed in nitrogen doped carbon nanotubes to obtain a material with a reasonable high surface area of 369 m 2 g −1 and pore size of ~6 nm [ 185 ]. Nitrogen doped graphene nanosheets is another precursor for loading molybdenum nitride [ 186 ].…”

The over-dependence on fossil fuels is one of the critical issues to be addressed for combating greenhouse gas emissions. Hydrogen, one of the promising alternatives to fossil fuels, is renewable, carbon-free, and non-polluting gas. The complete utilization of hydrogen in every sector ranging from small to large scale could hugely benefit in mitigating climate change. One of the key aspects of the hydrogen sector is its production via cost-effective and safe ways. Electrolysis and photocatalysis are well-known processes for hydrogen production and their efficiency relies on electrocatalysts, which are generally noble metals. The usage of noble metals as catalysts makes these processes costly and their scarcity is also a limiting factor. Metal nitrides and their porous counterparts have drawn considerable attention from researchers due to their good promise for hydrogen production. Their properties such as active metal centres, nitrogen functionalities, and porous features such as surface area, pore-volume, and tunable pore size could play an important role in electrochemical and photocatalytic hydrogen production. This review focuses on the recent developments in metal nitrides from their synthesis methods point of view. Much attention is given to the emergence of new synthesis techniques, methods, and processes of synthesizing the metal nitride nanostructures. The applications of electrochemical and photocatalytic hydrogen production are summarized. Overall, this review will provide useful information to researchers working in the field of metal nitrides and their application for hydrogen production.
