Post‐Synthetic Zinc Modifications to Correct Speciation in Ti‐MWW Zeolites for Catalytic Oxidation

Angewandte Chemie, EarlyView.
Post‐synthetic Zn modifications of Ti‐MWW zeolite catalysts exhibit improved catalytic properties in the selective oxidation reaction, namely the ammoximation reaction. The origin of the beneficial effect of Zn is related via an array of spectroscopic and microscopic techniques to the modification of extra‐framework TiO2 and TiOx clusters and the ...

Key Drivers of Activity and Selectivity in Cu‐Based Catalysts for Methanol Synthesis From CO2: Insights From Atomically Dispersed Promoters

Angewandte Chemie, EarlyView.
Mechanistic studies on model Cu─M/SiO2 catalysts (M = Zn, Ga, and In) reveal that promoters enable a formate spillover pathway from Cu to Mn+ (n = 2 or 3) sites. The promoter's electronic effect on formate bond strengths serves as a quantitative descriptor for activity and selectivity, balancing spillover dynamics with intermediate stabilization to ...

Active‐Site Photothermal Energy Utilization in PET Depolymerization

Angewandte Chemie, EarlyView.
Photothermal catalysis enables efficient PET depolymerization, yet the role of active‐site temperature remains unclear. A catalytic activity reversal between Pd–CNG and PdPOM–CNG is observed under thermal and photothermal conditions. Efficient nanoscale photothermal energy delivery raises active‐site temperature, compensates for lower intrinsic ...

Access to Unsupported Iminobismuthane and Tetraazabismole Species Enabled by a Rigid and Bulky Organobismuthinidene

Angewandte Chemie, EarlyView.
By employing a sterically bulky monocoordinate bismuthinidene, the synthesis and characterization of the first examples of an unsupported iminobismuthane and tetraazabismole was achieved via reactions with organic azides. The corresponding amines could be accessed by reduction, leading to the regeneration of the Bi(I) compound. Hence, we also highlight
