Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Pd and Pt nanoparticle loading improves room-temperature NO2 response, selectivity, and kinetics relative to pristine Cu3(HHTP)2.
Caveat: Humidity stability was not demonstrated; baseline resistance reached the 100 Mohm measurement limit at high humidity.
p008 · Conclusion · Figure 4 · Linked to 8 structured results
The Cu3(HHTP)2 framework structure is retained after Pd and Pt nanoparticle loading.
Caveat: XRD peaks of Cu3(HHTP)2 are weak after loading, but FT-IR and porosity data support retention.
p004 · Results and Discussion · Figure 3a,e · Linked to 4 structured results
The about 2 nm pores of Cu3(HHTP)2 confine Pd and Pt nanoparticle growth, yielding about 2 nm well-dispersed nanoparticles.
Caveat: Nanoparticle size is reported from TEM/HRTEM images; size distribution statistics are not tabulated.
p002 · Results and Discussion · Figures 1-2 · Linked to 3 structured results
Pd nanoparticles improve sensing through electronic sensitisation involving NO2 adsorption on Pd and Schottky junction modulation.
Caveat: The authors explicitly note Pd response is not solely related to charge transfer between NO2 and Cu3(HHTP)2.
p008 · Results and Discussion · Figure 5e · Linked to 3 structured results
Pt nanoparticles chemically facilitate NO2 adsorption on Cu3(HHTP)2, lowering the adsorption activation energy.
Caveat: Mechanistic assignment is inferred from kinetic fits and activation energies; oxidised PtO contributions are included in the measured sensor response.
