Summary: We disperse Pt single atoms on TiO2 thin films and evaluate the photocatalytic H-2 generation. We find that a minuscule loading of Pt single atoms is sufficient to achieve maximized H-2 production rate under common illumination intensities. The overall reaction rate is determined by charge carrier generation, rather than the density of co-catalytic sites.

Summary: The oleaginous microalga Scenedesmus sp. SPP was rapidly immobilized in oleaginous fungal pellets by utilizing their opposite surface charges. The microalgae-fungal (MF) pellets showed higher efficiency in improving the bioremediation of non-sterile secondary effluent compared to mono-culture. By coating the MF pellets with 0.4% chitosan, the removal efficiencies of COD, TN, and TP were significantly enhanced, likely due to better cell retention and nutrient adsorption and assimilation.

Summary: Metal halide perovskites (MHPs) have shown great potential as a new generation of photocatalysts due to their tunable band gap, wide visible light absorption range, and fast carrier transfer. However, their poor stability under water, oxygen, and high temperatures, as well as the recombination of photogenerated charges and weak oxidation activity, pose challenges for their development.

Summary: With the increasing consumption of fossil fuels, the rapid increase in CO2 emissions has led to energy crisis and climate problems. Converting CO2 directly to high-value chemical fuels through solar energy harvesting provides a solution to these problems. This review focuses on the physicochemical properties and synthesis methods of metal halide perovskites (MHPs), as well as the advancements in strategies for enhancing the photocatalytic CO2 conversion to solar fuels, such as size and facets effects, ion doping or exchange, anchored cocatalysts, semiconductor heterojunctions, and Pb-free MHPs. The challenges of stability and toxicity, photocatalytic activity and selectivity, prospects of theoretical calculations, and potential applications of MHPs in solar cell devices and catalysis are also discussed. This review sheds light on the development of efficient MHPs for industrial applications in CO2 reduction.

Summary: The energy consumption for building cooling is a significant part of global energy consumption, causing energy crisis and environmental deterioration. Passive radiative cooling has been considered a promising method with practical application potential. In this study, a superhydrophobic ZnO nanorods@cellulose membrane for efficient building radiative cooling was fabricated using an in-situ growth method and sodium laurate modification process. The membrane exhibited high reflectance and low thermal emissivity, resulting in a significant temperature reduction. Furthermore, its superhydrophobicity and flexibility make it suitable for various applications.

Summary: This study successfully synthesized biochar-supported sulfidated nano zerovalent iron (S-nZVI@BC) and demonstrated its effectiveness in the reductive degradation of soil-sorbed contaminants. The as-synthesized composite showed superior nitrobenzene (NB) removal and aniline (AN) formation efficiencies compared to S-nZVI alone. Furthermore, the addition of biochar enhanced the solubilization of NB from soil. Overall, this research highlights the potential of S-nZVI@BC in enhancing the in-situ remediation of NB-contaminated soil.

Summary: Alginate-based nanocarriers have great potential in the delivery of bioactive compounds. Calcium alginate and sodium alginate, as the most promising wall materials, are non-toxic, relatively cheap, simple to produce, and biocompatible and biodegradable. The review discusses different alginate-based nanocarriers and their entrapment of bioactives, as well as their bioavailability in the gastric environment. Alginate-based nanocarriers can be used as emulsifiers/encapsulants for various bioactives, including vitamins, minerals, peptides, essential oils, and carotenoids. The combination of alginate-based nanocarriers with other polysaccharides/emulsifiers is recognized as the most effective approach for the protection, delivery, and sustained release of bioactives.
