“…[24][25][26] Moreover, it is well known that the HER activity of single-component catalysts can be improved by constructing heterojunctions consisting of two or more different compounds. [27][28][29][30][31] This is due to the fact that heterojunction interfaces tend to expose more active sites and the electronic reconfiguration brought on by heterointerface coupling can optimize the energy of the reacting adsorbates, thus improving the catalytic activity and reaction efficiency. However, there have only been an extremely limited number of investigations on creating heterojunctions of MPS 3 and other compounds published up to now.…”

The fabrication of heterojunctions is an intriguing approach to boost the reactivity of catalysts. However, facile preparation of desirable heterojunction materials remains a challenge. Here, novel CoPS3/CoS2 heterojunctions are created by an intuitive phosphatization process on the basis of structurally flexible cobalt sulfide precursors. Significant stress effect exists at these heterogeneous interfaces, resulting in lattice distortions and the exposure of more active sites. The interface interaction also modifies the catalyst's electronic structure to improve its electrical conductivity and hydrogen adsorption capabilities. Notably, the overpotential of the CoPS3/CoS2 heterojunction for electrocatalytic hydrogen evolution reaction is just 36.3 mV, which is far superior to those of single‐component catalysts and competitive with comparable catalysts reported. This work not only offers an innovative electrocatalyst but also a strategy that can be used to create heterojunctions based on related transition metal thiophosphates.

“…The specific surface area, pore size distribution, and pore volume of (TiO 2 −Pt)/CeO 2 composite materials with varied TiO 2 proportions are measured via the N 2 adsorption-desorption test, with results displayed in Figure 5 . The isotherms of three catalysts belong to type IV and possess H3 hysteresis loops at relative pressure of 0.7–1.0 P/P 0 according to the IUPAC classification ( Figure 5 a), indicating the mesoporous structure of (TiO 2 −Pt)/CeO 2 [ 44 ]. The BET surface area of (0.3TiO 2 −Pt)/CeO 2 , (0.5TiO 2 −Pt)/CeO 2 , and (0.7TiO 2 −Pt)/CeO 2 is 101.88, 108.88, and 110.11 m 2 g −1 , respectively, while their corresponding pore size is centered at 14.36, 12.71, and 13.58 nm, and pore volume is 0.36, 0.37, and 0.35 cm 3 g −1 , respectively, as displayed in the BHJ pore size distribution curves in Figure 5 b.…”

Supported Pt-based catalysts have been identified as highly selective catalysts for CO oxidation, but their potential for applications has been hampered by the high cost and scarcity of Pt metals as well as aggregation problems at relatively high temperatures. In this work, nanorod structured (TiO2−Pt)/CeO2 catalysts with the addition of 0.3 at% Pt and different atomic ratios of Ti were prepared through a combined dealloying and calcination method. XRD, XPS, SEM, TEM, and STEM measurements were used to confirm the phase composition, surface morphology, and structure of synthesized samples. After calcination treatment, Pt nanoparticles were semi-inlayed on the surface of the CeO2 nanorod, and TiO2 was highly dispersed into the catalyst system, resulting in the formation of (TiO2−Pt)/CeO2 with high specific surface area and large pore volume. The unique structure can provide more reaction path and active sites for catalytic CO oxidation, thus contributing to the generation of catalysts with high catalytic activity. The outstanding catalytic performance is ascribed to the stable structure and proper TiO2 doping as well as the combined effect of Pt, TiO2, and CeO2. The research results are of importance for further development of high catalytic performance nanoporous catalytic materials.

“…Compared with traditional constructions, durability is greatly enhanced because of the much lower rolling friction coefficient in contrast to the planar sliding friction coefficient [91,92]. • Soft contact structure: Due to the significantly reduced physical frictional resistance between liquid and solid, surface wear is decreased, leading to enhanced material durability [93,94]. • Adding lubrication: Most TENGs function in conditions of dry friction.…”

The field of transportation plays a crucial role in the development of society. It is vital to establish a smart transportation system (STS) to increase the convenience and security of human life. The incorporation of artificial intelligence (AI) and the Internet of Things (IoT) into the traffic system has facilitated the emergence of innovative technologies like autonomous vehicles or unmanned aerial vehicles (UAVs), which contribute to the reduction of traffic accidents and the liberation of human driving time. However, this improvement involves the use of multiple sensor devices that need external power sources. As a result, pollution occurs, as do increases in manufacturing costs. Therefore, the quest to develop sustainable energy remains a formidable obstacle. Triboelectric nanogenerators (TENG) have emerged as a possible solution for addressing this problem owing to their exceptional performance and simple design. This article explores the use of TENG-based self-power sensors and their potential applications in the field of transportation. Furthermore, the data collected for this study might aid readers in enhancing their comprehension of the benefits linked to the use of these technologies to promote their creative ability.
