Summary: In this study, a thermo-switchable Pickering emulsion was developed for temperature-controlled catalysis. Thermoresponsive Janus silica nanosheets (JNSs) with a poly(N-isopropylacrylamide) brush on one side and a chiral salen TiIV complex on the other side were prepared. The JNSs exhibited temperature-sensitive wettability switching behaviors, allowing for reversible emulsification and demulsification. The smart JNSs enabled accelerated asymmetric sulfoxidation in water, followed by quick in situ-demulsification for complete separation upon heating.

Summary: This study investigated the mechanistic details of glucose photoreforming over TiO2 and Pt/m-TiO2 catalysts. The alpha-scission mechanism of glucose oxidation was confirmed by the formation of arabinose and formic acid in the initial oxidation step. The selectivity to sugar products and formic acid differed over Pt/TiO2 and TiO2, with Pt/TiO2 showing lower selectivity to formic acid due to enhanced adsorption/conversion. In situ ATR-IR spectroscopy revealed the presence of molecular formic acid and formate on the surface of both catalysts, suggesting the dominance of formic acid oxidation in glucose photoreforming.

Summary: Photoinduced hydrogen production is a promising green strategy for converting solar energy into chemical energy. This study successfully developed noble metal-free photocatalysts by combining different shape-controlled TiO2 nanoparticles and MoxC co-catalyst. The functional properties and efficiency of the composite materials were carefully assessed, and the engineered MoxC/TiO2 interfaces were found to be particularly active in the photocatalytic hydrogen production.

Summary: Platinum was incorporated onto titania-mesoporous carbon composite and tested for glycerol photoreforming. The high surface area of the mesoporous carbon promoted the dispersion of titania, while photodeposition led to preferential incorporation of platinum onto titania. The Pt/TiO2-MCH catalyst, with 18.4 wt% titania and 1.3 wt% platinum, showed a hydrogen production three times higher than the Pt/TiO2 catalyst after 12 hours.

Summary: This study demonstrates an improved selectivity in glucose photoreforming for coproduction of hydrogen and arabinose under neutral conditions using carbon quantum dots (CQDs) modified TiO2 composites. The colored CQDs in the composites enhance the glucose to arabinose conversion selectivity and efficient hydrogen evolution in water. The work not only offers new insights into CQDs-assisted biomass valorization and hydrogen coproduction, but also suggests a potential application for solar energy utilization in a noble-metal-free system.

Summary: This study synthesized biochars from olive stones and used them as supports for TiO2 and Pt. The results showed that the photocatalyst with a mesoporous structure and small particle size had better hydrogen production. The activity of Pt/TiO2-PyCF was almost 4 times higher than that of Pt/TiO2, indicating the positive effect of a well-dispersed TiO2 phase on a carbonaceous support.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.

Summary: This paper provides insights into the optimal configuration of CSP plants with different penetrations of wind power by proposing an unconstrained optimization model. The results suggest that large solar multiples and TES are preferred in order to maximize profit, especially when combined with high penetrations of wind and photovoltaic plants. Additionally, the study demonstrates the economy and feasibility of installing electric heaters (EH) in CSP plants, which show a linear correlation with the penetration of variable energy resources.
