    Abstract Fenton catalytic degradation of dimethyl sulfoxide (DMSO) by using liquid-phase pulsed high voltage discharge was carried out. The discharge was driven by a self-made pulsed power supply providing a pulse rising time of 400 ns, discharge repetition rate of 96.2 Hz, peak voltage of 20 kV. The side surface of discharge electrode was insulated in order to limit the discharge current, followed by estimating its effect on single pulse power. The effects of aqueous conductivity, Fe(II), and O2 flow rate on liquid-phase discharge induced DMSO degradation and aqueous conductivity on corresponding H2O2 yield were investigated. The concentrations and selectivities of intermediates of DMSO degradation, were also studied. The results indicated that when using the insulated electrode, single pulse power had a limiting value with increasing the aqueous conductivity; DMSO degradation rate was reduced with increasing the aqueous conductivity and O2 flow rate,whereas Fe(II) showed a Fenton catalytic oxidation of DMSO; 80% of DMSO degradation rate was achieved at the pulsed high voltage discharge time of 45 min and the resultant biodegradability was enhanced by at least 32%-48%; the maximum energy efficiency in G(37%) was 0.0087 mol/(kW x h). The study suggested that the liquid-phase plasma combined catalyst promised the potential of organic compound degradation.

    Abstract S.-Z. Qiao, X.-W. Du, and co-workers report on page 740 the preparation of nanoflake arrays (NFAs) with appropriate size and their unprecedented light absorption properties. Intriguingly, after a thin-layer of an organic absorber is loaded on NFAs, extraordinarily high absorption efficiency (95%) is realized. As a result, the hybrid solar cell consisting of NFAs and the organic absorber yields a photo-current that is ten times higher than that of the counterpart device with common planar structure.

    Abstract Cadmium chalcogenide nanocrystals (CCNCs) are regarded as promising materials for photoelectrochemical (PEC) water splitting. However, the relatively low PEC response and poor stability restrict their practical applications. In the present work, we demonstrate that a well-designed inverse opal structure (IOS) composed of CCNCs can achieve an unprecedentedly high photocurrent and hydrogen production rate. In particular, the IOS electrode remains stable during 3 h of continuous illumination, which is even superior to those photoanodes with surface passivation and/or co-catalysts. Quantitative investigation reveals that the IOS possesses high charge-separation efficiency and light-absorption capacity, which eventually result in excellent PEC performance.

    Abstract CdS nanoflake arrays (NFAs) exhibit unprecedented light absorption capability, and they can serve as a scaffold to load thin organic absorbers for extraordinarily high light absorption. As a result, the hybrid solar cell consisting of NFAs and organic absorber yields a ten-times high short-circuit photocurrent compared to the counterpart device with a common planar structure.
