Visible-light photocurrent response of TiO2–polyheptazine hybrids: evidence for interfacial charge-transfer absorption

“…51,52,[71][72][73] Broad absorption bands corresponding to the NH stretching vibrations are observed between 3350 and 3150 cm À1 , and manifold peaks arising from CQN and C-N vibrations are found between 1700 and 1100 cm À1 . [74][75][76] The polyheptazine layer at the surface of TiO 2 nanocrystallites is presumably very thin so that the XRD spectrum of the hybrid material shows only anatase peaks (see ESIw, Fig. 51,52,[71][72][73] The FTIR spectrum of the TiO 2 -polyheptazine hybrid is practically a sum of the IR spectra of the TiO 2 and polyheptazine components, plus the stretching CRN vibrations at 2200-2050 cm À1 suggesting the presence of cyanamide and/or dicyandiamide traces.…”

Laser ablation of molecular carbon nitride compounds

“…The pellet was mounted on a rotating target holder (1.5 rpm, operating distances 150 mm) inside an ultra-high vacuum (UHV) chamber and ablated by a horizontal line scan of a femto-second laser (516 nm, 442 fs) which is focused on the target surface. The laser power ranged between 30 Table 2 Relevant Raman and IR vibrational bands for dicyandiamide [45,46], melamine [47,48] and melem [37]. .…”

The effect of metal surfaces on the adsorption and degradation behavior of an epoxy/amidoamine system

“…A similar conclusion was drawn for the adsorption of ammonia on ZnO 29) . In addition, zinc was also found to react with a commonly used latent curing agent, dicyandiamide, and is reduced to a carbodiimide compound 25,30,31) . The durability of the adhesive bonds prepared with galvanized steel was closely related to the mentioned surface properties of zinc 25) .…”
