We elucidated the stimuli-responsive phase transition in a synthetic model of marginally stable proteins composed of poly(N-isopropylacrylamide) with incorporated redox-responsive sites. Redox-state changes in a single redox-responsive site were efficiently converted to hydration and dehydration of multiple monomer units within the polymer chain synchronized with electron transfer.

A sulfonic acid-functionalized conjugated organic polymer named BMS was synthesized to boost H2O2 photosynthesis. Sulfonic acid groups enhanced hydrophilicity, O2 adsorption, and charge transfer, enabling a H2O2 production rate of 2.59 mmol g-1 h-1 in air and pure water, and a rate of 3.08 mmol g-1 h-1 under O2-saturated conditions.

A novel and efficient method for the esterification of carboxylic acids with alcohols has been developed, utilizing carbon disulfide as a coupling agent. A wide range of aliphatic and aromatic carboxylic acids, including dicarboxylic acids, protected amino acids, and fatty acids, are well-tolerated under this protocol, delivering excellent yields. The key advantages of this method include low alcohol loading, excellent to quantitative yields, metal- and acid-free conditions, neutral reaction conditions, as well as a straightforward work-up and purification process.

Two-electron air electroreduction has shown low efficiency at the theoretical limit. Here, a Lewis basic CeO2 cocatalyst was used to expedite the reaction, achieving >90% Faradaic efficiency at the theoretical limit. Theoretical and experimental analyses demonstrate that the incorporation of CeO2 alters the electronic structure of ZnO, thereby enhancing selective oxygen adsorption.

We evaluated CO2 electroreduction differences of three materials in aqueous H-cell, gas diffusion electrode (GDE) half-cell, and full-cell electrolyzer devices. Mass-transport limited catalyst differences in H-cells become more apparent in gas-fed GDE half-cells; however, voltage contributions from device components can mask cathode differences in full-cell devices until high current density.

We report a one-step synthesis of lanthanoid-doped BiVO4 microswimmers that integrate photon upconversion and light-driven propulsion within a single particle. Yb3+/Er3+ doping enables near-infrared-to-visible upconversion, while BiVO4 provides photocatalytic propulsion. This straightforward strategy avoids multi-component assembly and opens up new opportunities for designing multifunctional photoactive microswimmers with intrinsic luminescence for potential use in environmental and biomedical applications.

The growing demand for sustainable energy solutions has led to significant research in photocatalytic water splitting, a promising approach for clean hydrogen production. Oxychalcogenide materials have emerged as a compelling class of photocatalysts due to their tunable electronic structures, various architectures, and favorable band edge positions for solar water splitting. This review provides a comprehensive analysis of recent advances in oxychalcogenide photocatalysts, emphasizing their structural diversity, composition–property relationships, and key design strategies. We highlight the impact of anion selection, cation contributions, charge carrier dynamics, and material stability on photocatalytic performance. Furthermore, we discuss innovative experimental approaches, such as surface modifications that have been employed to enhance activity. By consolidating existing knowledge and identifying critical parameters for optimization, this review aims to shed light on this class of photocatalysts and help guide the rational design of next-generation oxychalcogenide photocatalysts for efficient and scalable solar hydrogen production.

Core-shell and hierarchical Pd-Cu nanowires, exposing strained Cu(100) and Cu (100)/Cu(111) surfaces, respectively, were constructed. The hierarchical Pd-Cu demonstrated superior overall activity, ethylene selectivity, and reaction kinetics toward electrochemical CO2 reduction reaction. Theoretical calculations indicate the lattice-expanded Cu (100)/(111) interface effectively reduce the energy barrier for C2 production.

Hydrophobized metal-organic framework (MOF) of MIL-101(Cr) (M101) was elaborately constructed to encapsulate CdS quantum dots (QDs). The customized hydrophobic MOF shell shielded CdS QDs from exposure to moisture, and simultaneously quenched the holes of CdS through Z-scheme charge transfer, thus inhibiting CdS photocorrosion for efficient sunlight-driven aerobic oxidation.
