最近做了一批SBA-15,加入TEOS之后,40℃静置20h,100℃水热反应得到的,为什么100晶面的衍射峰会向左偏移,偏移了大约0.3°左右的样子,而且110,200不明显,或者看不出来。恳请大侠求解!!!(XRD扫描范围0.5-5.0°,Step Size: 0.01 deg. Scan Rate: 1.000000 Scan Mode: Continuous Wavelength: 1.540562) QQ图片2016030815...

The diffraction patterns of all CheMin samples are also characterized by a broad diffraction band centered near 30deg 2theta and by increasing diffraction intensity (scattering continuum) from approx.15deg to approx.5deg, the 2theta minimum. Both the broad band and the scattering continuum are ...
It was shown that: (1) when the plants were heated to 200deg C, they did not burn. At the temperatures of 250 or 450deg C, the plants burned; (2) comparison of the non-burned samples and non-heated plants showed their 13C-NMR spectra to be similar for lignin and especially ...
