Two Mn II coordination polymers based on the flexible bis(benzimidazole) and dicarboxylic acids, namely, [Mn(L1)(bpdc)(H 2 O) 0.5 ] n (1) and [Mn(L2)(Htbi) 2 ] n (2) [L1 = 1,4bis(5,6-dimethylbenzimidazol-1-ylmethyl)benzene, H 2 bpdc = 4,4Ј-biphenyldicarboxylic acid, L2 = 1,4-bis(5,6-dimethylbenzimidazole)butane, H 2 tbi = 5-tert-butyl isophthalic acid] were hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, as well as single-crystal X-ray diffraction. Both of the complexes crys-* Dr. G. Y. Dong Fax: +86-0315-2592170 E-Mail: tsdgying@126.com [a] College

The biomass of rice straw was chosen to prepare the biomass semi-cokes which are characterized by nitrogen adsorption/desorption and Fourier transformation infrared spectroscopy (FT-IR). The influence of biomass semi-cokes activity on pore structure and surface properties of the semi-cokes was investigated. Denitration and mercury removal experiments were carried out in a fixed-bed reactor. The results show that the active biomass semi-cokes have more specific surface area and micro-pore volume than the biomass semi-cokes. It has direct relationship between the NO and mercury adsorption capacity. It is supposed that oxygen-containing functional and basic groups may have dominant effect on the mercury removal from the glue gas.
