Problems solved by technology

At present, the common solution is surface modification or ion doping. However, surface modification is likely to cause problems such as competitive adsorption and occupation of active sites. Ion doping introduces a large number of electron-hole recombination centers, resulting in the catalytic Reduced activity and stability
