Abstract A facile and universal strategy is employed to synthesize Ag decorated NiCo layered double hydroxide (LDH) heterogeneous structure for the oxygen evolution reaction (OER). The nanoparticles are deposited on LDH nanosheets via a spontaneous redox reaction. synthesized Ag/NiCo achieves an overpotential of 460 mV at current density 1 cm −2 geo , surpassing that (722 mV). In anion exchange membrane water electrolyzer (AEMWE) with as anode Pt/C cathode, cell can deliver ultrahigh 5 low voltage 2.10 V. This superior nearly four times larger than AEMWEs other non‐precious electrocatalysts reported in literature under same effective area. Furthermore, it exhibits desired durability no performance decay over 300 h which almost six longer IrO 2 anode. Operando electrochemical impedance spectroscopy results reveal decoration facilitates active site formation reduces OER onset potential compared LDH. study showcases practical approach designing highly durable industrial hydrogen production.

Bismuth sulfide@bismuth nanorods (Bi2S3@Bi NRs) have emerged as promising photodynamic therapeutic agents due to Bi2S3@Bi being able produce reactive oxygen species from self-supplied O2. Combining photothermal and therapies with chemotherapy is attractive but difficult achieve. Here, we develop a subtle method wrap NRs mesoporous polydopamine, where drug doxorubicin hydrochloride can be loaded, thus providing multifunctional antitumor nanospheres. To our delight, the prepared triple-functional material exhibits excellent efficacy toward tumor cells under near-infrared light irradiation. This nanomaterial not only biocompatible also suitable for hypoxic microenvironments, having much better than single- or double-functional materials. study highlights great potential of combining photothermal, photodynamic, chemotherapies.

Abstract The development of bifunctional, non‐noble metal‐based electrocatalysts for hydrogen evolution reaction (HER) and oxygen (OER) through morphology electronic engineering is highly attractive efficient water splitting. Herein, hierarchical nanoarrays consisting crystalline cobalt phosphide nanorods covered by amorphous Fe‐doped nanocuboids (CoP/FeCoP x ) are constructed as bifunctional catalysts both HER OER. Experimental results theoretical calculations reveal that the exhibit balanced dual‐catalytic properties due to simultaneous introduction Fe doping phosphorus vacancies, leading an optimized structure CoP/FeCoP . Furthermore, made crystalline/amorphous heterostructures significantly enhance performance electrocatalysts. As a result, catalyst demonstrates remarkable in OER, with overpotentials 74 237 mV at 10 mA cm −2 1 m KOH, respectively, well low cell voltage 1.53 V alkaline overall This work integrates involving design vacancies electrolysis. It may open new route toward rational feasible fabrication high‐performance, multifunctional, energy conversion.
