DURING investigations of gas phase heterogeneous catalysis it is often necessary to demonstrate that the reaction products arise from the heterogeneous catalytic reaction and not from a homogeneous ...

IN recent years much attention has been given to the study of heterogeneous catalysis, and great advances have been made in our knowledge of the influence of surfaces in promoting chemical change.

According to evidence from our laboratory, acidic surfaces on atmospheric aerosols lead to potentially multifold increases in secondary organic aerosol (SOA) mass. Experimental observations using a ...

Interpretation of chemical rate selectivity data in homogeneous and heterogeneous reaction systems. Development and application of the theory of chemical kinetics, including collision, transition ...

The heterogeneous reaction of thiols with lead oxide to form insoluble lead thiolates is the basis for a new process that separates thiols from a hydrocarbon stream. The process uses inexpensive ...

The ease of separation of heterogeneous catalysts from the reaction environment makes them an essential component of simplified less energy intensive processes. Furthermore, newly designed catalytic ...

Groundwater comprises about 30 percent of Earth’s available freshwater; however, this vital resource is often contaminated by industrial or agricultural sources. The efficiency of existing groundwater ...

As global energy and environmental challenges intensify, solar-driven photocatalysis has emerged as a promising pathway for sustainable chemical conversion. Metal halide perovskites (MHPs), with their ...
