Kinetic Studies of Catalytic Ozonation of Atrazine

Croatica Chemica Acta, 2008
The aim of our work was to degrade atrazine by the ozone treatment of both a model and the original drinking water samples, using Pt-catalyst, and to evaluate the performance of this catalyst. The rate constant for the reaction of atrazine with ozone was determined in the model water sample.

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

Carbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide

Chemistry – A European Journal, EarlyView.
Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.
