                           OXFORD CATALYSTS GROUP PLC

                     ('Oxford Catalysts' or 'the Company')

                             Placing of New Shares

Oxford Catalysts Group PLC, the leading catalyst innovator for clean fuels, is
pleased to announce the conditional placing of 3,225,807 new ordinary shares of
1 pence each ('Ordinary Shares') at a price of £1.24 per share (the 'Placing')
with various funds managed by Pioneer Investments, a trading name of the Pioneer
Global Asset Management S.P.A group of companies. The Placing has raised £4.0
million for the Company.

Founded in 1928, Pioneer Investments has assets under management of over €232
billion (as at 31 March 2007), with a presence in more than 20 countries
worldwide. Pioneer Investments is the fund management arm of the UniCredit
Group, which is one of the largest banking and financial services organisations
in Europe, with a network of 7,200 branches in 60 countries.

The proceeds of the Placing will be used to strengthen the Company's position by
accelerating and expanding development in a number of additional areas which
have emerged since the IPO, including opportunities in Instant Steam and biogas
conversion.

In addition, various funds managed by Pioneer Investments have also agreed to
acquire 3,397,800 existing Ordinary Shares from certain shareholders, subject to
the Placing being admitted to trading on AIM.

Following the Placing and the acquisition of existing Ordinary Shares, various
funds managed by Pioneer Investments will have a disclosable holding of
6,623,607 Ordinary Shares, representing 16.33% of the issued share capital of
the Company as enlarged by the Placing.

Roy Lipski, Chief Executive of Oxford Catalysts said:

'I am pleased to welcome Pioneer Investments to the share register, having first
been approached by them earlier this year. We are grateful for their support and
the confidence that they have shown in our technologies and commercialisation
progress.

'We are raising new funds in response to a large order from Pioneer, which will
add to our strong shareholder base, reinforce the growing status of Oxford
Catalysts in the clean fuels market, and place us in a strong position to
exploit the wealth of opportunities now available to us.'

Each new Ordinary Share will rank pari-passu with all existing Ordinary Shares.
Following this issue of equity, there will be 40,566,990 Ordinary Shares in
issue. Application has been made for the new Ordinary Shares to be admitted to
trading on AIM; it is expected that such admission will be effective as at 
8 a.m. on 18th July 2007.

Notes to Editors


Oxford Catalysts Group PLC, the leading catalyst innovator for clean fuels,
designs and develops specialty catalysts for the generation of clean fuels from
both conventional fossil fuels and certain renewable sources such as biomass.
Its patent-pending technology is the result of almost 20 years of research at
the University of Oxford's prestigious Wolfson Catalysis Centre, headed by
Professor Malcolm Green, one of the world's most respected inorganic chemists.
Oxford Catalysts was founded by Professor Green and Dr Xiao in October 2004 and
was admitted to trading on the AIM market of the London Stock Exchange on 26th
April 2006, having raised £15m before expenses from a solid base of
institutional investors.

Oxford Catalysts' strategy is to license its catalysts for commercial
application by entering into co-development partnerships with leading
manufacturers, producers and suppliers in the petroleum, petrochemicals, fuel
cells, biogas, steam applications and catalysis markets.

Oxford Catalysts has two key platform technologies. The first is for a novel
class of catalysts made from metal carbides which, for certain reactions, can
match or exceed the benefits of traditional precious metal catalysts at a lower
cost. Applications of these metal-carbide catalysts include the removal of
sulphur from crude oil fractions (known as hydro-desulphurisation or HDS), the
conversion of natural gas or coal into virtually sulphur-free liquid fuels via
the Fischer-Tropsch reaction (known as the GTL and CTL processes respectively),
and the transformation of biogas (waste methane) into syngas - the building
block of liquid fuels.

The second platform relates to chemical reactions involving a liquid fuel
containing an alcohol (such as methanol), hydrogen peroxide and water. The
company's novel catalyst can be used to release hydrogen gas from this liquid
fuel, instantaneously starting from room temperature. This groundbreaking
hydrogen-on-demand technology has the potential to significantly accelerate the
commercial adoption of fuel cells in the portable and other mobile markets, by
providing the much needed source of cheap, safe transportable hydrogen.

Another of the company's catalysts can be used to produce superheated steam
(800c+) from the above fuel, instantaneously starting from room temperature.
Such portable high-temperature steam could have important applications in a
broad range of markets, from cleaning and disinfecting, to motive power and
electricity generation.
