Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Pd1.5%/Ti-MOF is selected as the optimum Pd loading for NB N-formylation because it reaches complete conversion with high N-formyl aniline selectivity under LED and sunlight.
Caveat: Pd2% also gives complete conversion and Pd2.5% gives slightly higher 1B selectivity but lower conversion.

Pd1.5%/Ti-MOF is recyclable and structurally stable over five photocatalytic cycles.
Caveat: Cycle-by-cycle numerical recycling values beyond the fifth-cycle text value are approximate from a bar chart.

XPS shifts and Pd 3d deconvolution support electronic interaction between Pd nanoparticles and Ti-MOF, forming a Pd-MOF interface.
Caveat: XPS deconvolution and SI surface survey/anchoring figure support the interface; exact structural position of all Pd NPs remains partly inferential.

Pd incorporation decreases Ti-MOF surface area and pore volume, consistent with partial Pd loading in or on the framework while retaining microporosity.
Caveat: The paper argues most catalytically relevant Pd is on the surface, while a small fraction may enter pores; the exact distribution is inferred from N2 sorption, TEM, and XPS.

HCOOH photodecomposition over Pd1.5%/Ti-MOF proceeds via a decarboxylation route to CO2 and H2; H2 is trapped at Pd sites as Pd-H and participates in nitroarene reduction.
Caveat: GC-TCD H2 and CO2 concentrations were read from rendered SI Figure S10; H2 amount is low and authors attribute this to Pd-site entrapment.

Pd incorporation improves charge separation and transfer in Ti-MOF, giving lower PL intensity, shorter TCSPC lifetime, larger photocurrent, and lower EIS arc radius.
Caveat: Fitted EIS resistance values are not reported; Nyquist arc extents are visual estimates rather than fitted Rct.
