This work seeks to elucidate intrinsic periodic trends for the epoxidation of cyclohexene by H₂O₂. Metallocalixarenes of Ti^IV, Zr^IV, Hf^IV, V^V, Nb^V and Ta^V have been grafted onto silica to yield a family of single-site metal oxide catalysts upon calcination. We further investigate surface modifications for improved selectivity and activity.
