a Time courses of urea production for NU-1000, Co-HHTP, NU-1000/Co-HHTP and NU-1000@Co-HHTP, b yield rates of different products on NU-1000, Co-HHTP, NU-1000/Co-HHTP and NU-1000@Co-HHTP, c wavelength-dependent AQY of NU-1000@Co-HHTP, d 1H NMR spectra of urea generated by using 14NO3- and 15NO3- as the feedstocks, e photocatalytic urea production over NU-1000@Co-HHTP under different conditions, f urea yield rates of NU-1000@Co-HHTP during recycling stability test, in situ FTIR spectra and corresponding contour projections of g, h NU-1000@Co-HHTP, respectively. Error bars represent the standard error of the mean from three independent experimental measurements. Source data for Fig. 5 are provided as a Source Data file.
