WebThe XRD results indicate that the copper films have a (111) texture. Moreover, the additives suppress the predominant (111) plane crystal growth and increase the rate of (220) texture crystal growth. The crystal size of the copper films was calculated using the Scherrer formula from the predominant peak. SEM and AFM studies reveal that these ... WebAug 25, 2015 · This work demonstrates that crystal facet modification greatly affects surface charge population of a photocatalyst. The better photoactivity of {010} dominant BiVO4 is attributed to prompt electron transfer facilitated by the presence of more photogenerated electrons on the larger {010} surface. Read more in J.
