Manipulation and/or conversion of sunlight energy are eternal research topics, since the inexhaustible solar energy is one of the most ideal candidates to conquer the increasingly terrible energy sources crisis. In this work, highly regular ZrC nanopatterns were assembled, by combination of an atomic layer deposition (ALD) and ultra-thin alumina membranes (UTAMs). The as-grown ZrC nanopatterns are in large area up to several square centimeters, and can be self-supported. Assisted with the sacrificed zinc oxide, size and spacing of the nanopatterns can be manipulated in even larger scale. Solar thermal property investigation shows that this kind of carbide of the transition metal can efficiently convert the sunlight into heat. This kind of nanopatterns has great potential in both solar-thermo usage and solar-thermo enhanced thermo-chromic smart windows.
