Construction and excellent photoelectric synergistic anticorrosion performance of Z-scheme carbon nitride/tungsten oxide heterojunctions

Abstract

The use of heterojunctions for metal corrosion protection is a highly innovative and challenging work. Based on the composition and structure of tungsten oxide-based heterojunction, Z-scheme heterojunctions were designed and...

Improved Interfacial Interactions of Dip Coatings by In Situ Introducing Silica to Enhance Corrosion Resistance and Metal Bonding Strength

“…In general, the R s , R ct , and coating resistance against ion transfer ( R p ) can be determined by locating the impedance intercept of the Nyquist plot from high frequency to low frequency with respect to the real axis. It should be noted that a large diameter in the capacitive loop corresponds to a high R p value, indicating improved corrosion resistance. − As shown in Figure a, the MEP-PTFE coating with a PTFE doping of 1.5 g had the largest capacitance loop diameter, indicating that it has the best anticorrosion performance among the MEP-PTFE coatings. The slope of the capacitive loop, which is considered a straight line in the high-frequency region, was increased and eventually stabilized at a constant value with the amount of PTFE doping increased, as shown by the Nyquist impedance magnification of the MEP-PTFE coatings at high frequency.…”

Design and enhanced anticorrosion performance of a Zn5Mo2O11·5H2O/h-BN nanocomposite with labyrinth of nanopores

“…15 A larger impedance modulus at a low frequency presents a better anticorrosion performance of coatings. 47 Fig. 8(a)–(d) shows the Bode diagrams of steel substrates coated with blank EP, ZMO/EP and ZMO/ h -BN/EP after being immersed in NaCl aqueous solution (3.50 wt%) several times.…”

Construction of a Novel Visible-Light-Driven Z-Scheme NiAl-LDH Modified (BiO)2CO3 Heterostructure for Enhanced Photocatalytic Degradation Antibiotics Performance in Natural Water Bodies

“…According to the discussion above, a novel Z-scheme , strategy for the enhanced photocatalytic capability of a NiAl-LDH/(BiO) 2 CO 3 heterojunction was proposed. If the formed heterojunction is type-II (Figure (a)), electrons will migrate from NiAl-LDH to (BiO) 2 CO 3 along the CB edges, while h + will move along VB edges in the opposite direction.…”
