A novel catalyst which integrates heterogeneous and homogenous Fenton reactions is designed and fabricated by encapsulating 2,5-dihydroxy-1,4-benzoquinone (2,5-DBQ) in ECDP-Fe3O4, a composite of Fe3O4 nanoparticles immobilized on a β-cyclodextrin polymer (ECDP) with ethylene diamine tetraacetic acid (EDTA) as cross-linking agent.

Hydroxyquinol, a common metabolite of aromatic compounds, is readily auto-oxidized to hydroxyquinone. Enzymatic activities that metabolized hydroxyquinone were observed from the cell extracts of Sphingobium chlorophenolicum ATCC 39723. An enzyme capable of transforming hydroxyquinone was partially purified, and its activities

Inelastic neutron scattering (INS) spectra of solid 2,5-dihydroxy-1,4-benzoquinone were measured and compared with IR and Raman data. The INS spectrum is very well reproduced in the region below 1000 cm(-1) by DFT calculations on the B3LYP/6-311++G** level using Gaussian and

In this paper, we report the Ab initio calculation and experimental investigation of the vibrational frequencies of 4,5-dihydroxy-1,2-benzoquinone and 2,5-dihydroxy-1,4-benzoquinone. The main IR and Raman absorption bands of them have been assigned, learned from other strong points to offset one
