Summary: This paper investigates the adsorption performance of silver-modified mesoporous materials in removing thiophenic compounds. The results show that the adsorption of thiophene by the sorbents involves S-Ag and pi complexation reactions, and the adsorption efficiency is greatly affected by benzene. XPS analysis reveals that silver interacts strongly with the carrier and forms Ag-O-Si bonds as the active centers for thiophenic compounds. The Mulliken charges of sulfur atoms have an impact on the interactions between silver and thiophene sulfur compounds.

Summary: Sun light-driven photocatalytic and photoelectrochemical water splitting have great potential for solar to chemical energy conversion. The incorporation of solitary photoelectrodes or dispersed photocatalysts mimics visible light harvesting and facilitates the activation of redox activities by transporting charge carriers.

Summary: Extensive research has been conducted on metal oxide-based supercapacitors in recent years, but their intrinsic conductivity and stability are still lacking. To address this challenge, 1D/2D heterostructure materials are being used to improve performance and stability by taking advantage of their morphologically tuned surfaces and superior electroactive sites. However, the sluggish faradaic reaction at the electrode/electrolyte interface hinders satisfactory performance. To overcome this, a novel 1D/2D heterostructure of ZnCo2O4 (ZCO) and GaN was designed, employing synergistic advantages of morphological nanoengineering and fast reaction kinetics of redox mediators, leading to excellent energy storage performance.
