  • A series of TiO2/SGFGDA composite photocatalytic materials were prepared using industrial solid waste Sangang flu gas desulfurization ash (SGFGDA) and industrial titanium gel (TG) as precursors via impregnation‑ loading method. Characterization results from X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and photoelectrochemical tests revealed that TiO2 particles were uniformly dispersed on the surface of SGFGDA, forming a tight and strong interfacial interaction between the two components, which effectively promoted the separation of photogenerated electron-hole pairs. The TiO2 loading amount significantly influenced the photocatalytic degradation performance of the composites toward formaldehyde (HCHO). The sample (TiO2/SGFGDA-40) with TiO2 loading amount (mass fraction) of 40% exhibited optimal HCHO degradation performance under ultraviolet light irradiation, with a degradation efficiency of 87% in 4 h. This performance was significantly superior to that of pure TiO2 and its physical mixture. Systematic comparative studies reveal that the composite obtained by combining SGFGDA with TiO2 outperformed conventional supports in terms of photocatalytic HCHO degradation. Moreover, it can be found that the photocatalytic activity of the flue gas desulfurization ash (FGDA) from different sources-based composites is closely correlated with the CaSO3·0.5H2O content in the FGDA. Furthermore, the above-mentioned powder composite with optimal performance was fabricated into a putty powder coating. The coating retained 80% of the HCHO degradation efficiency after 4 h of ultraviolet light irradiation and retained stable performance over five cycles. It showed good compatibility with common building additives, demonstrating promising potential for engineering applications. Under 72-hour solar irradiation, the optimal powder composite TiO2/SGFGDA-40 achieved 24% HCHO degradation efficiency, comparable to powdered P25 (26%). Its derived putty powder coating exhibited enhanced efficiency of 35%, significantly higher than the putty powder coating prepared by mixing SGFGDA and P25 (19%).
