Photocatalytic H2 evolution activities evaluation. a, b Typical time courses of H2 evolution upon AM 1.5, UV and Vis irradiations over 2DA (a) and 2DPA (b). c, d Wavelength-dependent QEs (blue dots) of 2DA (c) and 2DPA (d). The corresponding optical absorption spectra are superimposed for comparison. The error bars indicate the bandwidths of the filters used. e, f Cycling tests of photocatalytic H2 evolution upon AM 1.5 irradiation over 2DA (e) and 2DPA (f)
