Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

open access: yesSmall, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

Carbon‐Modified SnS2/g‐C3N4 S‐Scheme Heterostructure with Enhanced Interfacial Charge Transfer for Efficient Photocatalytic Reduction of Cr(VI) and 4‐Nitrophenol

open access: yesSmall, EarlyView.
The S‐scheme of SnS2‐C/g‐C3N4 heterostructure enables Photocatalytic Cr(VI) and 4‐NP reduction. ABSTRACT Hexavalent chromium (Cr(VI)) and 4‐nitrophenol (4‐NP) are persistent and highly toxic water pollutants that require efficient treatment under mild conditions. In this work, L‐cysteine‐derived carbon‐modified SnS2 (SnS2‐C) was prepared hydrothermally

Mg2+ Ions as Interfacial Charge Bridges for Enhanced Photocatalytic Hydrogen Evolution in Poly(Heptazine Imide)

open access: yesSmall, EarlyView.
Mg2+ confined within poly(heptazine imide) acts as a heterogenized interfacial charge bridge capable to couple synergistically the semiconductor with Pt co‐catalysts, thus enhancing hydrogen evolution. Through water polarization and hydroxide stabilization, a dynamic Mg2+‐OHδ−‐Hδ+‐Pt motif facilitates proton transfer and overcomes interfacial electron ...

Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

open access: yesSmall, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.

Resolving Real‐Time Interfacial Dynamics on Garnet‐Based Solid‐State Electrolytes via Snapshot Operando XPS

open access: yesSmall Methods, EarlyView.
This work establishes snapshot operando x‐ray photoelectron spectroscopy (XPS) as a compelling laboratory‐based technique for real‐time probing of dynamic interfaces in solid‐state batteries. By combining second‐scale temporal resolution with complementary HAXPES depth profiling, the methodology enables direct observation of electrochemical processes ...
