Balancing d‐π/d‐π* Interactions: Valence‐Engineered Pd/TiO2 for Photocatalytic Acetylene Semi‐Hydrogenation

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Photocatalytic acetylene (C2H2) semihydrogenation is a green route for ethylene (C2H4) production, yet the activity–selectivity trade‐off caused by imbalanced adsorption/activation of reactants and products remains a core challenge. Herein, we realize precise regulation of Pd oxidation states (Pd0, Pdδ+, and Pd2+) on anatase TiO2 nanocubes via

Injectable Piezocatalytic Heterojunction Triggers In Situ ROS Release Coupled With Immunogenic Cell Death for Hepatocellular Carcinoma Therapy

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The immunosuppressive milieu of hepatocellular carcinoma (HCC) remains a major obstacle to durable antitumor responses. Mechanical‐energy‐driven piezocatalysis provides a noninvasive means of inducing oxidative damage and immunogenic tumor destruction; however, inefficient utilization of piezoinduced charges and insufficient localization of ...

Sulfur Vacancy Modulation‐Induced Electronic Rearrangement in S‐Scheme BaTiO3@ZnIn2S4 Heterojunctions: Toward Synergistic Piezo‐Photocatalytic H2O2 Evolution

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.

Constructing Integrative Catalytic Pairs in Carbon Nanohorns for Enhanced Neutral H2O2 Electrosynthesis

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e−ORR) offers a sustainable and decentralized alternative to the anthraquinone process. However, conventional solo‐active‐site catalysts are intrinsically limited by scaling relationships, imposing a trade‐off between activity and selectivity.
