Summary: A series of polydopamine (PDA) surface-modified graphitized carbon nitride (g-C3N4) composites (CNPX) were successfully fabricated through a self-assembled method. The optimum material CNP40 exhibited 4.6-fold higher photocatalytic activity in generating H2O2 under visible-light irradiation compared to the pristine g-C3N4. Additionally, CNP40 achieved a significantly higher apparent quantum yield (AQY) of 1.91% under monochromatic irradiation of 420 nm, demonstrating 6.2-fold improvement compared to CN. The enhanced photocatalytic activity was attributed to the improved charge separation and dioxygen adsorption.

Summary: This study develops a photocatalytic hydrogen evolution system that dynamically and reversibly responds to changes in pH, showing that the pH influence on the system is mediated through the activation of a microhydrogel matrix. Experimental findings suggest that the scavenging of sulfite ions plays a crucial role in determining the rate of hydrogen production. Molecular dynamics simulations reveal a higher local concentration of sulfite hole scavengers at pH values below the pK(a) of the microgel, influencing the system's response to pH changes.

Summary: In this study, a low-consumption water purification system was constructed using a new dual-reaction-center catalyst (Mo-ZnS, MZS) with a confined nonequilibrium surface. The substitution of Mo for ZnS lattice enabled the Mo site to efficiently trap emerging contaminants (ECs) and transfer the electrons to the nonequilibrium surface through the oriented interface process (Mo-S-Zn bond bridge). The system utilized natural dissolved oxygen (DO) to generate hydrogen peroxide (H2O2) under trace H2O2 trigger without the need for light and electricity assistance, achieving a high yield of H2O2 and complete removal of ECs within 60 minutes.

Summary: This study presents a new type of memristor with a layered structure of GO/pyridinium/GO, which exhibits tunable bidirectional features. The insertion of organic pyridinium successfully controls the formation of conductive filaments during device operation, leading to progressive conductance regulation. The essential synaptic behaviors are replicated, and the emulation of brainlike learning-forgetting-relearning process is also implemented. In addition, the memristor shows instant responses to low operational voltages and short pulse widths. This research paves the way for GO-based memristors to achieve desirable features such as bidirectional tuning and fast speed switching, which are important for the development of bio-inspired neuromorphic systems.
