A bifunctional hydrogen evolution reaction and oxygen evolution reaction electrocatalyst by synergistically coupling a dual-active Co-based heterojunction (Co-CoO) with Ti3C2-MXene is proposed. The electrolyzer exhibits a low voltage of 1.55 V at 10 mA·cm−2 and remarkable durability.

We report a generalized strategy of assembling sandwich-like 0D/2D/0D heterostructures with barely covered surfaces and facilitated mass-transport channels, which render them highly suitable for surface-related electrochemical energy applications. As a proof of concept, the as-prepared MXene/NiFe2O4 and MXene/Fe3O4 heterostructures exhibit superior electrocatalytic and capacitive performances, respectively.

A series of protein nanocapsules with different surface chemistries are designed to systematically investigate the influence of specific functional groups on the cytosolic release kinetics. This work provides a new type of alternative self-assembled platform for gene delivery and details a framework on the future design of transfection agents.

The two-step O2/Ar plasma is reported to modify polytetrafluoroethylene (PTFE) surface for the first time. This CF4-free plasma etching produces high surface area as well as defective bonds, serving as charge trapping sites that intensified triboelectric charge density. These factors effectively enhance the triboelectric nanogenerato (TENG) power output density of PTFE nearly thirty times. Furthermore, the mechanical energy harvesting and keyboard sensing applications are demonstrated.

Dual-phase PdCu with remarkable biaxial strain is synthesized via a one-pot wet-chemical approach to boost formic acid oxidation. The interfacial biaxial strain induces the downshift of d-band center of Pd atoms and thus weakens the adsorption strength of undesired intermediates, which merits PdCu with superior catalytic activity and durability towards formic acid oxidation.

One-dimensional/two-dimensional (1D/2D) PANI/Ti3C2Tx nanohybrid was first synthesized through a simple assembly of polyaniline (PANI) nanofibers and Ti3C2Tx nanosheets. Benefiting from the high specific capacitance and ultrahigh rate capability with a fast kinetics of PANI/Ti3C2Tx, two assembled asymmetric supercapacitors (ASCs) deliver high energy and power densities as well as a good long-term stability, showing an exciting potential application in energy storage devices.

The nanofabrication of square-centimeter arrays of single-crystal gold nanoplates that combines nanoimprint lithography, directed-assembly, and a seed-mediated liquid-phase synthesis is demonstrated. Produced in high yield and with tunable optical properties, these nanoplates represent a viable building-block for on-chip plasmonic devices.

Nitrogen-doped carbon nanotubes (NCNTs) as a multi-functional support for CoSe2 nanoparticles boost the overall two-electron oxygen reduction reaction performances. The CoSe2@NCNTs achieve a high H2O2 selectivity of 93.2% with excellent durability. Effective electro-Fenton process enabled by such CoSe2@NCNTs is also demonstrated.

We reported a simple and green H2O2-assisted etching method that integrated nanostructure engineering with defect engineering to synthesize NiFe layered double hydroxide nanosheets with a porous structure, oxygen vacancies and Ni3+ defects on nickel foam (denoted as NiFe-LDHs/NF). Benefiting from the synergistic merits of these defects, the NiFe-LDH-NSs/NF exhibited an excellent oxygen evolution reaction (OER) activity.
