Mesoporous Silica‐Based Photocatalytic Materials for Solar Energy Storage and Utilization

open access: yesCarbon Energy, EarlyView.
ABSTRACT The efficient storage and application of sustainable solar energy has drawn significant attention from both academic and industrial points of view. However, most developed catalytic materials still suffer from insufficient mass diffusion and unsatisfactory durability due to the lack of interconnected and regulatable porosity.

Oxidation of Organometallic Platinum and Palladium Complexes Obtained from C−H Activation [PDF]

open access: yes, 2010
η^3-Cyclohexenyl and -indenyl Pt(II) and Pd(II) diimine complexes, which are generated via C−H activation of cyclohexene and indene by Pt and Pd hydroxy dimers, are selectively oxidized by Br_2, Na_2PtCl_6, and CuCl_2 to give halogenated organic products

Visible‐Light‐Driven Cycloaddition of CO2 with Epoxides Catalyzed by Recyclable Mg2⁺/TiO2 Photocatalyst Operating at Room Temperature

open access: yesChemistry – A European Journal, EarlyView.
A recyclable Mg2⁺/TiO₂ photocatalyst enables the cycloaddition of CO₂ with epoxides under visible light at room temperature, providing a sustainable route to cyclic carbonates without the need for solvents or harsh conditions. The catalyst shows a broad substrate scope, excellent yields, and recyclability, including successful gram‐scale synthesis ...

Structure and mobility of cyclohexane as a solvent for Trans-Polyisoprene

open access: yes, 2002
Solutions of {\it trans}$-$polyisoprene in cyclohexane are investigated in atomistic detail at different compositions at two different temperatures. We investigate the influence of polymer concentration on the dynamics of the solvent molecules and the ...

Anthraquinone Sulfonates as Water‐Soluble Photocatalysts: Synthetic Applications and Perspectives

open access: yesChemPhotoChem, EarlyView.
The development of photochemistry in water is rapidly advancing, and the demand for water‐soluble photocatalysts is increasing. Accordingly, anthraquinone sulfonates are interesting options for the activation of organic molecules through H‐atom transfer, proton‐coupled electron transfer, or the generation of reactive oxygen species.
