In this work, sol–gel combustion synthesis of spinel CoCuMnOx was reported. X-ray diffraction (XRD) and Fourier transformation infrared spectroscopy (FTIR) techniques were used to study the reaction processes. The as-synthesized spinel CoCuMnOx was further characterized by XRD, X-ray photoelectron spectroscopy, and field-emission scanning electron microscopy. The CoCuMnOx powders with a deep black hue were then used as solar energy-absorbing additive to make a novel kind of spectrally selective paint coatings. The solar absorptance (αs) and the thermal emittance (T) of the coatings were determined from the corresponding diffuse reflectance spectra in the 0.3–20 m range. The optimum selective sample exhibited values of αs=0.928 and 100=0.198. Besides ideal optical properties, the coatings also show excellent long-term stability, which is confirmed by results of accelerated tests established by IEA-SHC Task X, indicating that they could be a good alternative to the materials present today in the market.
