Summary: This article proposes a NO2- sensing platform based on surface plasmon resonance (SPR) enhanced oxidase-like activity, which has outstanding selectivity, sensitivity, and stability. By utilizing the oxidase-like activity based on ZnS decorated on Ag nanowires (Ag@ZnS), electrons are efficiently generated on the surface of ZnS and then transferred into the hot electrons of Ag with the help of localized SPR excitation, greatly oxidizing the colorless TMB to produce dark blue oxTMB. The addition of nitrite selectively reacts with oxTMB to generate diazotized oxTMB, resulting in a visual color change.

Summary: Proton exchange membrane fuel cells (PEMFCs) have high efficiency and nonpollution characteristics, but the stability issue of Pt-based catalysts is a major constraint to their widespread deployment. This review discusses how to improve the stability of Pt-based catalysts for the oxygen reduction reaction (ORR), covering the physical chemistry behind catalyst degradation and design strategies for enhancing stability.

Summary: In this study, PdW metallene-constructed sandwich-like nanosheets were prepared via a wet-chemical method, showing excellent electrocatalytic activity and durability in direct formic acid fuel cells. The enhanced catalytic activity is attributed to the unique nanosheet structure providing appropriate distances for bridge adsorption, while the improved durability is due to modification of the Pd electronic structure by the introduction of W. This work offers a low-Pd-loading, highly active, and stable bifunctional catalyst for direct formic acid fuel cells.

Summary: Alloying Pd with Cu in the form of two-dimensional nanodendrites enables highly stable and selective formate production, thanks to the combined electronic effect and nanostructuring effect, with remarkable catalytic performance under the working potential as cathodic as -0.4 V. This is rationalized by computational simulations showing that Cu atoms weaken the *CO adsorption and stabilize the *OCHO adsorption on neighboring Pd atoms.

Summary: Defect and interface engineering are effective strategies to improve the activity of metal sulfides, but the practical application is limited by low conductivity and volume fluctuation. By anchoring Zn-defective ZnS nanoparticles on the surface of NiCo2S4 nanosheets, the NiCo2S4/ZnS hybrids exhibit outstanding oxygen evolution performance with an ultra-low overpotential of 140 mV. The anchored ZnS nanoparticles inhibit volume expansion of NiCo2S4 nanosheets during cycling.

Summary: Lattice engineering on specific facets of metal catalysts is crucial for enhancing catalytic performance, as shown by a two-step method developed to expand the lattice on Pt(100) and Pt(111) facets. This lattice expansion significantly promotes alcohol oxidation reactions on both Pt(100) and Pt(111) facets, with impressive mass-specific activities achieved on the Pt(111) facet. Density functional theory calculations suggest that enhanced OH adsorption is responsible for the improved catalytic performance. These findings pave the way for enhancing the electrocatalytic activity of nanomaterials and designing highly efficient catalysts.

Summary: An efficient in situ etching strategy is employed to transform part of the pristine NiFe-MOF into active NiFe(OH)(x) and simultaneously induce the exposure of abundant defective areas, which not only facilitates the electron transfer efficiency for the oxygen evolution reaction (OER), but also enables the accessibility to further anchor Ru, leading to enhanced OER activity.
