“…In fact, TMCs (such as Ti 2 C, V 2 C and Ti 3 C 2 ) with -OH and -O on their surface are the basis of their metallicity, which causes charge transfer and transport. In addition, oxygen atoms which on the surface of TMCs provide active sites for HER, because the interaction between O atoms and H atoms on the surface of TMCs promotes the removal of hydrogen [119][120][121].…”

As a new member in two-dimensional materials family, transition metal carbides (TMCs) have many excellent properties, such as chemical stability, in-plane anisotropy, high conductivity and flexibility, and remarkable energy conversation efficiency, which predispose them for promising applications as transparent electrode, flexible electronics, broadband photodetectors and battery electrodes. However, up to now, their device applications are in the early stage, especially because their controllable synthesis is still a great challenge. This review systematically summarized the state-of-the-art research in this rapidly developing field with particular focus on structure, property, synthesis and applicability of TMCs. Finally, the current challenges and future perspectives are outlined for the application of 2D TMCs.

Carbon dioxide (CO2) is regarded as a major contributor to global warming and the climate crisis. To mitigate its negative impacts, a potential strategy is adopted, namely converting CO2 into renewable fuels or valuable chemicals. Because of the sluggish thermodynamic and kinetic processes, catalysts (photocatalysts or electrocatalysts) are essential during CO2 reduction. In this review, fundamental concepts, catalytic principles and reaction pathways related to photocatalysis and electrocatalysis for CO2 reduction are provided, along with a survey of the progress in the rational design of new photocatalysts and electrocatalysts for CO2 reduction. Discussions in the field are mainly focused on the design strategies of catalysts that have been introduced to increase visible light excitation, improve charge separation and enhance CO2 adsorption of photocatalysts and alter electronic and geometric properties of electrocatalysts. Finally, recommendations and outlook for improving the selectivity of CO2 reduction and in achieving efficient, stable and selective CO2 photocatalysts or electrocatalysts are pointed out. © 2020 Society of Chemical Industry

“…Currently, several alternatives to Pt-based electrocatalysts such as transition metal-organic frameworks, 6,7 transition metal phosphides, 8,9 and transition dichalcogenides, 10,11 have been exploited for hydrogen production. [12][13][14][15][16][17][18][19][20][21] Pyrite-nickel diselenide (NiSe 2 ) has been widely employed for the electrocatalytic HER because of its high activity and durability in alkaline and acidic medium. 22-29 22-29 However, bulk NiSe 2 has a small electrochemically active surface area and low electrical conductivity, which limit its catalytic applications.…”

Electrochemical water splitting is known to be one of the most potential pathways for hydrogen generation. However, this process is limited by the sluggish cathodic hydrogen evolution reaction (HER) kinetics. Nitrogen-doped materials have been exploited for the development of efficient electrocatalysts because of their tunable electronic properties. Herein, we illustrate a facile route to construct the core-shell architecture in NiSe 2 @nitrogen-doped carbon (NiSe 2 @NC) as efficient catalysts for the HER. NiSe 2 @NC samples were prepared through a two-step process involving pyrolysis and selenization at various temperatures from a nitrogen-rich Ni-based metal-organic framework (MOF) precursor. NiSe 2 @NC-500 C was considered as the optimal sample because it showed outstanding catalytic properties for the HER with low overvoltages of 161 and 220 mV to deliver a current density of 10 mA/cm 2 in acidic and alkaline solutions, respectively. In addition, NiSe 2 @NC-500 C exhibited excellent stability after 2000 cycles and 12 h of operation. The high catalytic performance was attributed to the synergistic effect of the core-shell structure and the carbon layers doped with high pyridinic-N content, which play a vital role in providing a large number of active centers, imparting high conductivity, and enhancing the durability of the electrocatalyst. This account may open an approach to the design and fabrication of low-cost electrode materials for HER. K E Y W O R D S core-shell structure, electrocatalysts, hydrogen evolution reaction, nickel diselenide Ha Huu Do and Quyet Van Le contributed equally to this work.
