However, it remains challenging to regulate the electronic configuration of B-site elements via A-site doping. In this study, we have reconstructed the electron configuration of B-site elements in high-entropy perovskites through Sm doping, and obtained high-entropy perovskite oxides La_1-xSm_x (Mn_0·2Fe_0·2Co_0·2Ni_0·2Cr_0.2)O₃ (LaSmTMO₃−x) with abundant valence states. The fabricated LaSmTMO₃−0.2 exhibits high specific capacitance of 1367.3 F g⁻¹ at 0.5 A g⁻¹. Besides, the asymmetric supercapacitor (ASC) based on LaSmTMO₃−0.2 exhibits an impressive energy density of 41.2 Wh kg⁻¹ at a power density of 400 W kg⁻¹, with a specific capacity retention of 87.1 % after 10000 cycles. The experimental results demonstrate that superior supercapacitor performance can be attributed to electron rearrangement induced by Sm doping, leading to the formation of active metal species with multiple oxidation states. Simultaneously, Sm doping significantly improves structural integrity, electronic conductivity, and ion transfer kinetics.

Therefore, a series of strategies have been developed for the preparation of CoAl₂O₄ pigment including common solid-phase method, liquid-phase and gas-phase technologies to meet the requirements of different application fields. However, the relevant applications of CoAl₂O₄ pigment are restricted at a certain degree due to the high cost derived from the scarcity of cobalt sources as well as the aggregation of CoAl₂O₄ particles during the high-temperature crystallization process. Interestingly, incorporation of stable inorganic substrates facilitates the decrease in the production cost and the control of the size and blue intensity of CoAl₂O₄ nanoparticles, especially incorporation of natural or waste nonmetallic mineral resources. Therefore, this review provides an overview of the recent advance in the synthesis, relevant applications and color regulation mechanism of CoAl₂O₄ pigment combining with the literatures and our research achievements. It is mainly focused on the synthesis mechanism of different methods, and the relationships between the structures and the application performances, especially the structural composition and color performance of the designed CoAl₂O₄/silicate hybrid pigments.

Quaternary TMDs have a general formula of M_1-xN_xX_2(1-y)Y_2y, where M and N are transition metals and X and Y are chalcogens. Thus, quaternary TMDs are versatile nanomaterials that exhibit tremendous potential for fine-tuning and optimizing their electrocatalytic performance through composition modulation, as shown by both theoretical and experimental studies. Additionally, additive manufacturing techniques such as 3D printing are emerging as powerful tools for fabricating structurally complex, compositionally tunable TMD-based electrodes with enhanced HER performance. The integration of 3D printing with advanced TMD synthesis methods enables the design of customized electrocatalysts, offering improved charge transport and catalytic activity for sustainable hydrogen production.

In this study, we investigated the impact of metal dispersion differences on the catalytic activity of CeO₂-supported clusters and atomically dispersed Pt catalysts from the perspectives of oxygen vacancies and metal-support interactions. The results indicated that the adsorption capacity of CO on the catalyst surface was significantly influenced by the oxidation state and aggregation of Pt, with atomically dispersed Pt⁰ exhibiting a stronger affinity for CO. The metal-support interaction was evident in the formation of Pt-O-Ce composite bonds resulting from the incorporation of Pt ions into the CeO₂ lattice, which enhanced Pt accessibility on the CeO₂ surface.

Undercoordinated Pt clusters led to strong CO binding and high CO vibration frequencies, while the presence of Pt^δ+ weakened CO adsorption but promoted carbonation reactions.
