The (111) peak is located between the standard fcc Co and Ni patterns, which indicates the formation of alloy.
“Specifically, the (111) peak located between the standard fcc Co (PDF. No. 89-7093, 44.226o) and Ni (PDF. No. 70-0989, 44.604o) patterns, which indicates the formation of alloy [40, 41].”
From Synthesis of Co2Ni/reduced graphene oxide composite aerogels as efficient hydrogen evolution catalysts (2022) · cites this paper as [40]
The Results and discussion section (page unavailable) reports a Co–Ni coordination shell in the Co–Ni–B catalyst, supporting an association between the metals. It does not report a (111) diffraction peak between the standard fcc Co and Ni positions or use that peak to establish alloy formation; its XRD discussion instead describes the sample as amorphous. (LLM, conf=0.78)
Experimental — accuracy not yet measuredThe activity of Co2Ni/5rGO is comparable to well-studied metal sulfide and phosphide catalysts and superior to the Co-30Ni-B catalyst.
“studied metal sulfide and phosphide catalyst and is superior”
From Synthesis of Co2Ni/reduced graphene oxide composite aerogels as efficient hydrogen evolution catalysts (2022) · cites this paper as [40]
The Results and discussion report HER performance for Co-30Ni-B, and Table S6 gives its overpotential at several current densities. The paper therefore supports using Co-30Ni-B as a benchmark, but our copy does not assess Co2Ni/5rGO or establish that it is superior to Co-30Ni-B or comparable to metal sulfide and phosphide catalysts. (LLM, conf=0.86)
Experimental — accuracy not yet measuredThe TOF number increases ~12% compared to the Co-30Ni-B electrocatalyst prepared by the similar NaBH4 reduction method (0.145 s−1 atom−1 at η=250 mV).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
