XPS data of MXene catalyst

Data contain results from XPS measurement of the Ti3C2Tx MXenes produced via acidic etching aluminum from MAX Phase (Ti3C2-Al-Ti3C2-Al-Ti3C2) using 48% HF etching agent (MXene HF). The X-ray spectroscopy (XPS) measurements were conducted using Mg Ka (hn = 1253.6 eV) radiation in a Prevac (Poland) system equipped with a Scienta SES 2002 (Sweden) electron energy analyzer operating with constant transmission energy (Ep = 50 eV). The analysis chamber was evacuated to a pressure below 5 × 10−9 mbar.

本数据集包含以48%氢氟酸（HF，MXene HF）作为刻蚀剂，从MAX相（MAX Phase，Ti3C2-Al-Ti3C2-Al-Ti3C2）中刻蚀铝制备得到的Ti3C2Tx MXenes的X射线光电子能谱（X-ray Photoelectron Spectroscopy, XPS）测试结果。本次XPS测试采用Mg Kα辐射（光子能量hν=1253.6 eV），测试在波兰Prevac公司的测试系统中完成，该系统配备瑞典Scienta SES 2002型电子能量分析器，运行于恒定透射能量模式（Ep=50 eV）。测试分析室的真空度被抽至5×10^−9 mbar以下。
