Ag2S composite materials were synthesized on oxidized polypropylene using chem. bath deposition method and their properties were explored using XRD, XPS, AFM and UV-Vis.  Polypropylene surfaces were modified using soln. methods to introduce hydrophilicity via carboxylic group formation which resulted in Ag2S film deposition and adhesion.  These films showed slightly sulfur enriched compn. from XPS anal. with the sulfate-like species forming, presumably at the oxidized polymer surface sites.  Ag2S particle growth mechanism included nucleation and rather large (few μm) aggregate formation eventually covering the complete polymer surface, as inferred from AFM anal.  Absorption edge of the composite material shifted toward the higher wavelength in UV-Vis spectrum with the no. of Ag2S exposure times showing a decreasing bandgap and the possibility of obtaining tunable optical property Ag2S-polymer composites using CBD methods.

Cuprous oxide films with [100], [110] and [111] orientation and variable thickness were electrodeposited by redn. of copper(II) lactate on com. available copper plates.  After initiation of the electrochem. CO2 redn. by these oxide structures, the selectivity of the process largely depends on the parent Cu2O film thickness, rather than on the initial crystal orientation.  Starting with thin Cu2O films, besides CO and hydrogen, selective formation of ethylene is obsd. with very high ethylene-to-methane ratios (∼8 to 12).  In addn. to these products, thicker Cu2O films yield a remarkably large amt. of ethane.  Long term faradaic efficiency anal. of hydrocarbons shows no sign of deactivation of the electrodes after 5 h of continuous expt.  Online mass spectroscopy studies combined with x-ray diffraction data suggest the redn. of the Cu2O films in the presence of CO2, generating a nanoparticulate Cu morphol., prior to the prodn. of hydrogen, CO, and hydrocarbons.  Optimizing coverage, no. d. and size of the copper nanoparticles, as well as local surface pH, may allow highly selective formation of the industrially important product ethylene.
