Summary: The commonly used Ag/AgCl wire quasi-reference counter electrode in the quantitative scanning micropipette contact method may leak Ag+ into the electrolyte solution, leading to interference in potential and generation of faradaic current. By using a leak-free Ag/AgCl electrode or increasing the distance between the electrode and micropipette tip droplet, the contamination of Ag+ can be eliminated, allowing accurate measurement of corrosion potentials during oil-immersed scanning micropipette contact method measurements.

Summary: In this study, a Z-scheme Ag/SnS2/g-C3N4 heterojunction photocatalyst with excellent photocatalytic performance was prepared. Silver nanoparticles were deposited in the SnS2/g-C3N4 composite through UV photoreduction. The photocatalytic properties of the fabricated material were characterized and its application in Rhodamine B degradation under low-power visible light irradiation was investigated. The results showed that the ternary material with a mass ratio of SnS2: g-C3N4 of 5:95 and a silver doping amount of 0.0022wt% exhibited the highest photocatalytic activity, being 9.09 and 5.73 times higher than that of single g-C3N4 and SnS2/g-C3N4, respectively. The improved photocatalytic activity was attributed to the Z-scheme heterojunction, localized surface plasmon resonance (LSPR) caused by deposited silver, and efficient separation of photoelectron-hole pairs.

Summary: This study demonstrated a rapid and efficient control method to prevent the spread of Aspergillus flavus spores in air using plasmonic composites. The composites, composed of Ag-AgCl nanoparticles and tetrahedral alpha-Fe2O3, showed a prevention rate of 93.65 +/- 1.53% under visible light irradiation. The prevention activity was attributed to the intrinsic disinfection, electron sink, and localized surface plasmon resonance effect of Ag. The composites also exhibited high activity (90.52 +/- 1.26%) in preventing Aspergillus flavus spore spread during peanut storage. These findings provide useful strategies for preventing Aspergillus flavus contamination and controlling toxic fungi.

Summary: Photocatalysis and piezocatalysis are important catalytic processes widely used in the fields of energy and environmental restoration. Photocatalysis is limited by the rapid recombination of electron-hole pairs, while piezocatalysis can achieve high-efficiency energy conversion through mechanical energy. Piezo-photocatalysis can combine the advantages of the two to improve catalytic efficiency, but there is still a vast knowledge gap for its design, applications, and prospects.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
