Stable Ti(3+) self-doped TiO(2) with tunable phase composition and highly efficient visible-light photoactivity (ca. 32.7 times stronger than an undoped sample for ˙OH formation) was synthesized via a facile metallic zinc-assisted method. The surface species can be stabilized by Zn doping, the photocatalytic selectivity regulated composition.

Electrocatalysis is critical to the performance displayed by sulfur cathodes. However, constituent electrocatalysts and reactants have vastly different molecular sizes, which ultimately restrict electrocatalysis efficiency hamper device performance. Herein, authors report that aggregates of cobalt single-atom catalysts (SACs) attached graphene via porphyrins can overcome challenges associated with catalyst/reactant size mismatch.

Red phosphorus (RP) is a promising anode material for use in lithium-ion batteries (LIBs) due to its high theoretical specific capacity (2596 mA h g–1). However, the practical of RP-based anodes has been challenged by material's low intrinsic electrical conductivity and poor structural stability during lithiation.

Two-dimensional amorphous photonic materials are created, which do not possess any long-range order but have only short-range order. Our calculation of the multiple-scattering method shows that, for S-polarized waves, these gap that is independent incident directions. Even though detailed structures different with each other, they a common gap, if same Based on our studies it may be confirmed first band crystals comes mainly from order, while higher-order gaps related to The measured...
Nonstoichiometric compounds are widely used in contemporary energy technologies due to their high surface polarity, tailored electronic structure, electrical conductivity, and other enhanced properties. However, the preparation of such nonstoichiometric can be complicated and, some cases, uncontrollable dangerous.

The catalytic activities displayed by single-atom catalysts (SACs) depend on the coordination structure. SACs supported carbon materials often adopt saturated structures with uneven distributions because they require high-temperature conditions during synthesis. Herein, bisnitrogen-chelated Co that are coordinatively unsaturated prepared integrating a complex into conjugated microporous polymer (CMP-CoN2). Compared analogues, i.e., tetranitrogen-chelated (denoted as CMP-CoN4), CMP-CoN2...
