The retention of specific surfacearea of Pt on Pt-Fe--Co/C is 20% higher than on Pt/C after an accelerated aging test. The anchoring of Pt on carbon surface by Fe and Co is thought to play a main role for the improvement of Pt--Fe--Co/C performance.

High specific area dimolybdenum nitride(up to 140 m2/g) has been synthesized by temperatureprogrammed topotactic reaction between MoO3 and NH3.The synthetic conditions of high surface area Mo nitride(usually,SBET>100 m2/g) were quite difficult and the amount of starting material MoO3 in each batch was much less than one gram.However,some synthetic conditions have been greatly improved in our experimets.Heating rate of the reaction segment was increased from the original 0.6 K/min to 1 K/min.Space velocity of NH3 was only one-tenth of that in the reported methods and the amount of precursor MoO3 approached 3 grams.It was revealed that space velocity of ammonia,elevated temperature rate and particle size of MoO3 were very important for producing high surfaceγ-Mo2N.The XRD result indicated that(200) plane of high surface area γ-Mo2N was more intense than that of low surface area γ-Mo2N.The intensities ratio of(200)/(111) was larger than 2.4 for the highest surface area γ-Mo2N(Mo2N-1).There was a regular change between surface area and pore diameter distribution.The percentage of micropore volume in the range of 2-3 nm was graduallyincreased with increasing of surface area.At the same time, the nitriding process of MoO3 was studied and it was found that MoO3 was essentially transformed into γ-Mo2N at 773 K.This temperature for the synthesis of high surface area γ-Mo2N was 200 K lower than that reported in the literature.

通过程序升温控制的MoO3与NH3的Topotactic反应,合成出钝化后比表面达140m2/g的γ-Mo2N。研究发现NH3空速、升温速率、前身态MoO3粒度等对高比表面γ-Mo2N的形成影响很大。γ-Mo2N的比表面与孔径分布呈一定的规律性变化。XRD测试结果表明高比表面γ-Mo2N与低比表面γ-Mo2N的衍射峰强度有很大差异。同时文中对MoO3的氮化过程进行了探讨,结果表明MoO3在773K时已生成高比表面的γ-Mo2N,比文献报道的合成温度低200K左右.

A series of porous adsorbents with high specific area were synthesized by Friedel - Crafts alkylation of chloromethylated polystyrene with aromatic hydrocarbons. The research results showed that specific surface area was obviously influenced by reaction conditions including the used hydrocarbon and solvent. This kind of polymeric adsorbents could adsorb phenol with high capacity.
