Two independent peer-reviewed papers, both published by Elsevier in 2026, characterise magnesium hydrogen-storage systems built with the Pd/MWCNT catalyst we supply. Below are the full citations with DOIs, the measured results, and — the part that matters most for due diligence — what the papers themselves say about where the material came from and what its specification is.
Buyers evaluating a hydrogen-storage material get told a lot of numbers by a lot of suppliers. Very few of those numbers have a citable source behind them.
Ours do. Both papers went through peer review at Elsevier journals, both name the material's manufacturer in the methods section, and both are permanently citable by DOI. If your technical team wants to check our claims, they do not have to take our word for anything — they can read the papers.

The two 2026 papers study palladium on carbon nanotubes. This earlier paper studies palladium on graphene — a different carbon support in the same AZ31 magnesium system, by the same group and with the same industrial co-author.
That is worth knowing for two reasons. First, it shows the catalytic effect is not an artefact of one particular support. Second, we supply both carbon materials: the Pd/MWCNT composite, and a few-layer graphene characterised at 5–8 layers with Raman verification. If your programme wants to compare supports rather than accept ours, we can supply both sides of that comparison.
Read it with the right weight. This is a shorter paper in a smaller journal than the two 2026 studies, and it is Scopus-indexed rather than SCIE Q1. We list it because it is real and relevant, not because it carries the same evidential weight — and we would rather rank our own evidence honestly than present three papers as if they were equal.

This paper states the palladium supplier explicitly in its Materials section:
“Palladium (Pd) particles were purchased from Top Nano Technology Co., Ltd., Taipei, Taiwan with 99.9% purity.”
That is an independent, third-party record of the purity grade our manufacturer supplies — written by a research group, not by us, and verifiable by anyone in one click.
| Absorption | 3.91 wt% in 60 minutes; 5.60 wt% under isothermal conditions at 375 °C |
|---|---|
| Desorption | 3.90 wt% released in 60 minutes (first-cycle activation) |
| Activation energy | 123.25 → 104.58 kJ/mol with 8 wt% WS₂ NT/Pd addition |
Read the scope correctly. This study uses tungsten disulphide nanotubes with palladium, not our Pd/MWCNT composite. Top Nano Technology supplied the palladium particles here, not a finished composite. We list it because it independently documents our manufacturer and its purity grade — not because its performance figures belong to our product. Those are in papers 1 and 2.
This is the passage that matters. In the Materials section of the 2026 Journal of Energy Storage paper, the authors describe where the nanotubes came from and what they measured:
The pristine MWCNTs were acquired from Top Nano Technology Co. Ltd. and demonstrated an average tube diameter of roughly 9.5 nm coupled with a high Brunauer–Emmett–Teller surface area of 250–300 m²/g. … This hybrid additive, supplied by the same manufacturer, consisted of 5 wt% palladium nanoparticles supported on 95 wt% MWCNTs and was produced by a wet-chemical deposition route that yielded crystalline Pd uniformly anchored to the nanotube surfaces.
Those figures — 9.5 nm tube diameter, 250–300 m²/g, 5/95 Pd/MWCNT — are the same figures on our technical datasheet. An independent research group measured them and published them. That is a stronger form of evidence than a supplier datasheet on its own, and it is the reason we point technical buyers here first.
