The Electrochemical Development of Pt(111) Stepped Surfaces and Its Influence on Methanol Electrooxidation

Table 2

Weighted ratio for the reflections in pc Pt, CT Pt, Pt F100, and Pt F111 electrodes.

	Pt bulk	pc	CT	F100	F111
𝐼𝑤(200)/𝐼𝑤(111)	1.00	3.34	3.12	2.44	0.32
𝐼𝑤(311)/𝐼𝑤(111)	1.00	2.84	2.94	2.21	0.06
𝐼𝑤(220)/𝐼𝑤(111)	1.00	9.61	2.46	5.19	0.10
𝐼𝑤(111)/𝐼𝑤(222)	1.00	0.57	1.09	0.87	0.75

Note: we consider reflection (200) as a representative of reflection (100).
