Surface-enhanced Raman spectroscopy (SERS) is a powerful technique that has found applications in many research fields. As promising alternatives to the current most popular plasmonic metal SERS
substrates, semiconductor SERS substrates have many appealing attributes. However, they permit signal enhancement only to analytes
adsorbed chemically on their surface, which means that semiconductor-based SERS can only be used for studying model analytes
such as dyes or thiols. Using volatile organic compounds (VOCs) as
an example, we demonstrate for the first time the detection of
non-adsorbing analytes on ZnO nanoparticles. Specifically, this
was achieved by coating ZnO nanoparticles with ZIF-8 shells, which
enriches VOC molecules and dampens the decay of the electromagnetic field around their surface, thereby significantly boosting their
electromagnetic enhancing capability such that it permits signal
enhancement for non-adsorbing analytes. Importantly, the MOFcoating strategy is universal, which means that it may enable the
detection of a wider variety of non-adsorbing analytes where conventional semiconductor-based SERS fails.

Achieving carbon neutralization by CO2 photoreduction (CO2PR) has attracted extensive attention. However, limited selectivity and harsh reaction conditions impede its practical application. Herein, we introduced a hydrogen storage material, ammonia borane (NH3BH3, AB), as mild proton–electron pair (adsorbed H atom, *H) donors, to realize synergistic hydrogen evolution and selective photocatalytic CO2 reduction to HCOOH. A preeminent HCOOH generation rate of 5237.8 μmol g–1 h–1 (with a HCOOH selectivity of 99.67% in carbonaceous products) was obtained. Intriguingly, *H provided by AB could accelerate selective HCOOH generation over Cu2O/TiO2 by promoting intermediate *HCOO generation in kinetics, and AB adsorption on Cu/TiO2 surface could also reduce the activation energy of HCOOH production in thermodynamics. Furthermore, some other similar *H donors have performed equally well in selective HCOOH, thus providing guidance for the design of a high-performance CO2PR system over the consideration of *H protons to meet the demand of sustainable development in the future.
