Fig. 8 (a)–8(c) show the waveform analysis of CuO/ZnO/CNTs at RT, 300 °C, and 600 °C from which the roughness of the sample surfaces can be inferred. As shown in Fig. 9, the EDX spectrum of CuO/ZnO/CNTs confirmed the existence of expected elements such as Zn, O, Cu, and CNTs in the composite. Given that a small amount of doped CuO …
Cupric oxide (CuO) is a semiconductor that exhibits p-type conductivity, crystallizes in the monoclinic structure and has a band gap of 1.5 eV [9]. Zinc oxide …
In this work, a novel 0D/3D CuO/ZnO heterojunction was obtained via in situ deposition of CuO nanoparticles on the flowerlike ZnO surface using the wet chemistry method. After depositing CuO ...
The AuPd/ZnO–CuO catalyst also shows good selectivity toward DHA and the highest DHA yield of 65.3%, which is at the top level among the reported results. Through STEM-EDS, XRD and Raman analyses, we find that ZnO–CuO is a composite oxide and that Zn and Cu elements in the ZnO–CuO support are uniformly distributed. Furthermore, HRTEM, EPR ...

1825 — The Erie Canal is completed opening a water route from the Great Lakes to New York City and the Atlantic Ocean. 1831 — The mechanical reaper is invented by Cyrus McCormick. 1837 — A blacksmith named John invents the steel plow. 1844 — The telegraph is invented by Morse.
To date, solar energy generation devices have been widely studied to meet a clean and sustainable energy source. Among them, water splitting photoelectrochemical cell is regarded as a promising energy generation way for splitting water molecules and generating hydrogen by sunlight. While many nanostructured metal oxides are …
The catalytic conversion of CO 2 into value-added fuels is a promising strategy for mitigating energy crisis. Cu/ZnO is extensively used for CO 2 hydrogenation to methanol (CH 3 OH) but still generally suffers from low conversion and selectivity. To enhance the conversion and selectivity, novel floral CuO–ZnO@ZIF-8 catalysts were …
