Special Issue Information

Dear Colleagues,

Transition metal selenides are compounds composed of transition metals (elements from the d-block of the periodic table) and selenium. Transition metal selenides possess stable physicochemical properties, abundant diversity in terms of material structures, and tunable electronic structures. They can form a wide range of material structures, including layered structures, nanostructures, and heterostructures. This diversity allows for tailored properties and functionalities, allowing them to be versatile for different applications. For instance, transition metal selenides exhibit certain potential applications in electrocatalytic hydrogen and oxygen reduction reactions, as well as in sodium/potassium-ion batteries.

Chemiluminescence (CL) is regarded as a better method for the detection of reactive oxygen species (ROS). However, the weak CL intensity prevents its further application. Many nanomaterials have been developed to enhance CL intensity, and mixed-ligand MOFs incorporating additional metals or organic ligands exhibit high efficiency in catalyzing. In this work, one kind of bimetallic mixed-ligand metal–organic framework (Ni-Co m-MOF) was synthesized using solvothermal methods. The material was morphologically characterized and demonstrated to be a dense and spherical flower-like structure. The addition of Ni-Co m-MOFs significantly enhanced the CL intensity of the luminol-H2O2 system by nearly 2,000-fold. The enhancement was found through further research as hydrogen peroxide was catalyzed to create hydroxyl radicals, etc., which reacted more easily with luminol. Herein, significant enhancement of the CL system by Ni-Co m-MOFs was identified, which provides ideas for improving the sensitivity and signal-to-noise ratio development of CL detectors. Full article

A key research focus at present is the exploration and innovation of electrode materials suitable for energy storage and conversion. Molybdenum-based sulfides/selenides (primarily MoS2 and MoSe2) have garnered attention in recent years due to their intrinsic two-dimensional structures, which are conducive to ion/electron transfer or insertion/extraction, making them promising candidates in electrocatalytic hydrogen production and sodium-ion battery applications. However, their inherently poor electronic structures have led most research efforts to concentrate on modifications aimed at enhancing their performance in hydrogen evolution reactions (HERs) and sodium-ion batteries (SIBs). Owing to their remarkable chemical inertness, expansive specific surface areas, and tunable pore architectures, carbon-based materials have garnered significant attention in research. The utilization of biomass as a renewable and environmentally sustainable precursor offers considerable benefits, including abundant availability, ecological compatibility, and cost-effectiveness. Consequently, recent scholarly endeavors have concentrated intensively on the synthesis of valuable carbon materials derived from renewable biomass sources. This review addresses the scientific challenges related to the development of electrode materials for HERs and SIBs in electrochemical energy storage and conversion. It delves into the recent focus on the two-dimensional transition-metal chalcogenides, particularly MoS2 and MoSe2, and the difficulties encountered in modulating their electronic structures when applied to HERs and SIBs. The review proposes the use of eco-friendly and widely sourced biomass-derived carbon (BMC) as a supporting matrix combined with MoS2 and MoSe2 to regulate their structures and enhance their electrocatalytic activity and sodium storage performance. Additionally, it highlights the existing challenges faced by these BMC/MoS2 and BMC/MoSe2 composites and offers insights into future developments. Full article
