Summary: Photocathode-based photoelectrochemical (PEC) sensors can avoid hole oxidation reactions and expand the application of PEC sensors in bioanalysis. In this study, a cathodic PEC sensor based on BiOI NSAs integrated with AuNPs on ITO electrode was fabricated. The AuNPs enhance the light absorption of BiOI NSAs and improve charge separation efficiency, promoting the PEC activity. Dopamine enhances the photocurrent by forming a charge-transfer complex on the BiOI NSAs surface. The PEC sensor shows promising results for dopamine detection in real samples, demonstrating the potential of BiOI-based materials in cathodic PEC biosensing.

Summary: A new ternary structure was designed to enhance the sensing properties of WS2 nanosheet-based gas sensors at room temperature in self-heating mode. SnO2 nanowires were added to WS2 nanosheets and Au nanoparticles were deposited on the surface of the resulting composites. The presence of SnO2 nanowires effectively enhanced the diffusion and adsorption of gas species, while the chemical sensitization of Au contributed to an enhanced response to CO gas. The results showed the potential of the Au-decorated SnO2-WS2 as a low-power, low-voltage CO gas sensor in wet environments.

Summary: In order to improve the gas sensitivity of NO(2) room-temperature sensors based on reduced oxide graphene (rGO), ternary hybrids were synthesized by combining different contents of rGO, ZnO rods, and noble metal nanoparticles (Au or Ag NPs) to utilize the advantages of each component. The presence of rGO in the ZnO-rod/rGO hybrid facilitated the diffusion of gas molecules by preventing rGO stacking and creating a porous structure. Among the tested hybrids, Ag@ZnO rods-2% rGO and Au@ZnO rods-2% rGO exhibited better gas-sensing properties for low concentrations of NO(2), with higher response and shorter recovery time.

Summary: Fundamental structural modification techniques of nanomaterials can be used to control the electronic structure of active sites and improve electrocatalytic activities. Appropriate surface reconstruction is necessary to overcome large electrochemical overpotential. Understanding fundamental structural modification mechanisms, such as the Janus structure, spillover effect, d-band center shift theory, and interfacial coupling, is essential. The Mott-Schottky (M-S) effect is a fundamental interface and valence engineering strategy that has gained interest recently due to its ability to enable mass transport, regulate the density of states, enable rapid electron transfer via band bending, and create a synergistic effect at the metal-semiconductor interface.
