Measurements of 31 P MAS NMR of adsorbed trimethylphosphine oxide indicated that the -milled h-BN had weak acid sites, comparable to those in . Despite its weak basicity, the -milled h-BN showed high activity and selectivity toward β-nitroalkenes for the nitroaldol reaction Henry reaction and the Knoevenagel condensation

· Alumina-supported silver catalysts Ag/Al2O3 derived from impregnation, a semiwet method, and water-free - were investigated for the selective catalytic reduction of NOx by ethanol. It was found that Ag/Al2O3 catalysts with the highest NOx reduction efficiency can be obtained via impregnation and the semiwet method but not by water-free
