The reported hydrometallurgy processes suffer from slow reaction kinetics and high thermodynamic barriers of water anodic oxidation, resulting in intensified competitive oxidation reactions of Pb²⁺ and H₂O molecules with low OER selectivity and lead recovery efficiency. Herein, we proposed a multi-metallic electrocatalyst, IrFe@Co-NCB, with optimized electronic and interfacial structures. The synergistic doping of Ir and Fe within the Co-NCB support enhances charge transfer and intermediate adsorption, promoting selective OER while suppressing PbO₂ deposition, thereby boosting reaction kinetics and selectivity and substantially lowering the overall energy consumption. As a result, the catalyst achieves a low OER overpotential of 265 mV@10 mA cm⁻² and a high Ir mass activity of 2.404 A mg⁻¹ in 1.0 M methanesulfonic acid (MSA), along with excellent long-term stability.

Herein, we report a novel strategy for the design of chiral nanomaterials by exploiting the precise tuning of the chemical composition of the nanocrystal. In this way, we successfully optimized the chiroptical activity in a broad compositional space of ternary and quaternary I-III-VI quantum dots (QDs) based on silver, copper, and indium sulfides. Our research reveals a clear threshold for chirality in relation to the chemical composition of the luminescent multinary nanocrystals. In particular, the magnitude of the chiroptical activity is directly related to the trivalent indium content, and only QDs produced in the compositional space of the indium-rich MIn₅S₈ phases (M = Ag, Cu) exhibit chiroptical activity, whereas the indium-poor MInS₂ counterparts remain consistently achiral. This compositional control of chirality arises from the distinct surface coordination environments, which govern the binding affinity and orientation of the chiral ligands on the QDs' surface, as demonstrated by computational studies.

Herein, we report a facile approach to the synthesis of colloidosomes with excellent sealing performance and tunable hydrophilicity. Our approach is based on the silica-stabilized Pickering emulsion templating, interfacial sol-gel reaction of TEOS and subsequent APTES grafting for surface hydrophilic modification. The size of colloidosomes agrees with the Pickering emulsion droplet and can be adjusted by changing the amount of silica. Notably, unlike other reported colloidosomes, the hydrophilicity of the synthesized colloidosomes can be controlled through the addition amount of APTES and their transfer into an aqueous medium can be readily achieved without any other steps. The colloidosomes demonstrated efficient encapsulation of hydrophilic active ingredients and feature a robust shell, enabling the high retention of enzyme activity (lipase) in practical liquid detergent applications. In contrast with unencapsulated lipase, colloidosome-encapsulated lipase demonstrated superior cleaning efficacy.
