Any idea what this catalyst actually is, perhaps a link to a paper, or even just an actual abstract?

  My skim-fu was weak. Thanks for pointing that out.

I think this is the paper: http://pubs.rsc.org/en/content/articlepdf/2016/ta/c6ta02876d http://pubs.rsc.org/en/content/articlepdf/2016/ta/c6ta02876d Highly active and durable self-standing WS2/graphene hybrid catalysts for the hydrogen evolution reaction

Is it this paper? https://scholar.google.com/citations?view_op=view_citation&hl=en&user=uVxFD-sAAAAJ&sortby=pubdate&citation_for_view=uVxFD-sAAAAJ:KqnX2w3egDsC https://scholar.google.com/citations?view_op=view_citation&h...

Abstract: A variety of catalysts have recently been developed for electrocatalytic oxygen evolution, but very few of them can be readily integrated with semiconducting light absorbers for photoelectrochemical or photocatalytic water splitting. Here, we demonstrate an eﬃcient core/shell photoanode with a highly active oxygen evolution electrocatalyst shell (FeMnP) and semiconductor core (rutile TiO2) for photoelectrochemical oxygen evolution reaction. Metal−organic chemical vapor deposition from a singlesource precursor was used to ensure good contact between the FeMnP and the TiO2. The TiO2/FeMnP core/shell photoanode reaches the theoretical photocurrent density for rutile TiO2 of 1.8 mA cm−2 at 1.23 V vs reversible hydrogen electrode under simulated 100 mW cm−2 (1 sun) irradiation. The dramatic enhancement is a result of the synergistic eﬀects of the high oxygen evolution reaction activity of FeMnP (delivering an overpotential of 300 mV with a Tafel slope of 65 mV dec−1 in 1 M KOH) and the conductive interlayer between the surface active sites and semiconductor core which boosts the interfacial charge transfer and photocarrier collection. The facile fabrication of the TiO2/FeMnP core/shell nanorod array photoanode oﬀers a compelling strategy for preparing highly eﬃcient photoelectrochemical solar energy conversion devices.

  I don't think so, Haiqing Zhou is not on that paper. Zhifeng Ren has a number of papers in this space.
