A breath of fresh air: Mesoporous manganese oxide (γ-MnO2) was deposited with gold nanoparticles by vacuum-UV-assisted laser ablation, resulting in very strong metal–support interactions. The composite was found to remove a wide range of volatile organic compounds (and NOx and SO2) from air as well as catalyze their decomposition.
